How to use Rest API with Python

Most of the web services in today’s digital world make their data accessible to third-party applications through an application programming interface (API). To build these APIs we need some architecture style.REST is one of the most popular architecture styles to build APIs and Python is probably the best choice to get data from REST APIs and also for building our own Python REST APIs.

If you are a developer (especially a python developer ) and looking for a basic guide to learn how to use rest API with python then you have landed in the right place where you will learn about rest API with python in a very simple way.

What is APIs?

API is the acronym for Application Programming Interface. The API act as an interface by which one application makes their data accessible to third-party applications.

The most common use of APIs is to retrieve data from remote websites, by making a request that is used all over the web. The most common API usages that we all see every day is “log-in using Facebook(Facebook Login API)/Twitter/Google/Github���. Instead of directly logging in to users’ social media accounts, applications use APIs to authenticate the user with each login. 

What is a REST Architecture

REST stands for Representational state transfer which is a software architectural style of APIs for web services.REST consists of a set of constraints designed to simplify software architecture for Client/Server communication. 

Some of the architectural constraints of REST are as follows:-

Stateless: The server won’t maintain any data from the requests coming from the client-side. The session state is stored only on the client-side.

Client-server: The client who is responsible for the user interface, and the server who is responsible for the backend and data storage must be independent of each other,

Cacheable: The data  that will be retrieved from the server must be cacheable either by the client or by the server

Uniform interface: A uniform interface should be provided by the server for accessing resources without defining their representation.

Layered system: The client may indirectly access the resources present on the server via other layers such as a proxy or load balancer.

For more info check Wikipedia.

REST APIs 

We already discussed that APIs are used to retrieve data from remote websites. But the question is how do we make a request to a remote web server and retrieve data? Well, that is done by making use of the URL endpoint that is where the API is being served from where each URL is called an HTTP request and the data that gets sent back is called a response.

The HTTP Request

The HTTP Request consists of the following components:

Endpoint:- The URL that indicates what data you are interacting with. The root endpoint is the starting point of the API from where the user is requesting. For E.g.- https://ift.tt/3AdzIzz.

/students is the endpoint, https://ift.tt/2YoHQA3 is the starting URL.

Method:- REST APIs provide methods to enable Create, Read, Update, and Delete functionality. The methods used by REST APIs are as follows:-:

GET – Retrieve data

PUT – Replace data

POST – Create data

DELETE – Delete data

The Response

For every request, a response will be received from the API. 

For an example:- The curl command on the terminal can be used to make a GET request to the Open Notify API that gives information about astronauts who are currently in space:

curl -X GET "<a href="http://api.open-notify.org/astros.json">http://api.open-notify.org/astros.json</a>"

Above you can see a response in JSON format that gives the data about those astronauts.

How to Use Python Requests with REST APIs

Now, let’s understand how you can integrate with a REST API using Python Requests. Firstly, make sure you have Python and pip installed on your host machine(In this tutorial I am using Linux) and after that follow the following steps:-

Step 1:- Install the python requests module with pip command on your terminal:

pip install requests

Now you can start using Python Requests for interacting with a REST API, you should import the Requests library into that particular python script that you want to use it in:

import requests

Step 2:- Next, you have to Request Data With GET

The GET method is used to retrieve data for any resources we are interested in from a REST API. Here we are going to work with https://randomfox.ca/, which will give you a random picture of little foxes each time.

copy the API from the website

We have to create an object or variable that’s going to store all the content that we will get from the above website’s server in response to the GET request, including headers and the data payload. 

response = requests.get("https://randomfox.ca/floof") print(response.status_code)

You can access a lot of things from the object among which the line print(response.status_code) will return a status code whenever you are going to make HTTP requests that will inform you how the request went. The Default is 200 or “Ok” which means the response went well and all the information returned is fine

 Other HTTP code tables are as follows:-

Step 3:- Retrieve the data you want to (here, the random pic of the fox)

So now we are going to use the JSON function which is a part of the request. All or most of the APIs use a  language called JSON(somewhat looks like python dictionary) which is a type of standard to communicate with API information which will be in the same format as given on the website:-

The content of the request can be accessed in a few ways such as:- 

response.content() # Return raw bytes of data payload response.text() # Return string representation of data payload,as it is string we can’t pull any data response.json() # Convenient when the API returns JSON

response.content()

If we use this we will get the data in raw format and the output will look like this:-

response.text()

If we use this our data will be in string format and the output will look like this:-

response.json()

So to get what we need i.e the random fox picture we have to use the JSON function.We have to replace our print(response.status_code) (from step 2) with the print(response.text()) and our final code will like the following:-

Import requests response = requests.get("https://randomfox.ca/floof") print(response.json())

You will get the following output:-

Click on the link and you will be redirected to a random fox image like the following:-

Alternate way/Another method

When we are printing with JSON we’re actually working with a dictionary. So we can create a new variable(fox_img) and set it with response.json() . This response.json() will get the dictionary and put it in the new variable(fox_img) from where now we can take any of the data and print it out.

For example:- We have two keys “image” and ���link” that we can use to modify our code like the following:-

Using image key

As we have used the image key, the API will go and look for the image key in the dictionary and prints its value.

Code:-

import requests response = requests.get("https://randomfox.ca/floof") fox_img=response.json() print(fox_img['image'])

Output:-

So we have got only the string that links to our image and not the whole dictionary. 

Using link key

Here we have used the link key so the API will now go and look for the link key in the dictionary and prints its value.

Code:-

import requests response = requests.get("https://randomfox.ca/floof") fox_img=response.json() print(fox_img['link'])

Output:-

Here we got only the link as it was the value of the link key.

Conclusion

This was a very short and beginner-friendly tutorial to give you a basic idea of how you can use rest API with python, you can do a lot more things with APIs, Once you get the data you can use it in your own way and apply it on any of your projects to do wonders.

What is AWS Free Tier & How to use that

Anything free is always something we want to get, that is why Amazon offers their AWS free tier. It provides 12 months of Free Tier account to new users so that they can get hands-on experience with all the AWS cloud services. If you get the free tier account, all the AWS services will be offered free of cost to you for a year with some limitations.

this article is intended to provide all the answers which you might have regarding the AWS free tier account. How to get access, how long does it last, are there any limitations of a free account.

What is the AWS Free Tier?

Amazon Web Services is one of the most emerging platforms offering services (by using all kind of technologies) that meets the need of any type of business. The AWS Free Tier automatically gets activated on each new AWS account. This lets the user explore all the AWS services free of cost up to specified limits for each service.

What are the Types of Free Tier? How long does it last?

 There are 3 types of free tiers offered by AWS, which are as follows:-

Short term trials: These are short-term trials where the customer are free to use the AWS Services for a specified period of time 

12-Months free: These offer customers to use the AWS services for free up to limited usage for 12 months since the initial sign-up date, after the 12 month period is expired the customer has to pay standard rates.

Always free: These offers let all the AWS customers to use AWS services free of cost up to specified limits for a lifetime. It doesn’t expire at the end of the 12-month AWS Free Tier term.

For knowing more about AWS charges or pricing see AWS Pricing.

Limitations of AWS Free Account

It’s actually free but there are some limits to it as it is not possible to give unlimited services for free of cost if they do so then the company will surely break down. Some services are free forever with some limitations whereas some are not, you can track your Free Tier usage with the usage alerts. If you exceed the free tier limits, you have to pay the standard or pay-as-you-go service charges.

Do you need a credit card to use it?

Yes, you need to give the payment details such as a credit or debit card to use the Free Tier, so that in case you exceed any usage limits, you can be charged. But if you don’t exceed any limits, you won’t be charged.

Any students, entrepreneurs, or small businesses are eligible to use the free tier AWS.

Can you host a website using the AWS Free Tier?

Yes, you can host a website using it for a year at least.

AWS Account Identifiers

There are 2 types of unique ID that are assigned to each user’s account by AWS.they are as follows:-

An AWS account ID:- This AWS account ID is a 12-digit number such as 123456780123 used for constructing Amazon Resource Names (ARNs). 

A canonical user ID:- This AWS account ID is a 64-digit hexadecimal encoded with a 256-bit number which is used in an Amazon S3 bucket policy for cross-account resource  

How To Create Free Tier Account

Visit the AWS Free Tier webpage & click on Create a free account option.

Provide your mail id that was never registered with Amazon AWS before then type a password and confirm it and give an AWS account name that you can also change after you sign up.

Select your AWS type (Profesional/ Personal), provide other details such as name, address, phone number, state, city, Accept the Terms and conditions and then click Create Account and Continue

Lastly, you have to give the payment details so that after the trial is over they can charge you. After you are done with everything, your  AWS Free Tier account will get activated.

Conclusion

After understanding the AWS free tier we can conclude the following points:-

We don’t get all the AWS services under the AWS Free Tier.

Some services under Free Tier have usage limits so if the limit exceeds for the particular user then they will be charged at standard rates.

What is CTE in SQL?

In this article, we will discuss CTE or common table expressions introduced in SQL Server 2005 that are also used to get hierarchical queries.

What is a common table expression or CTE?

CTE stands for common table expressions that are temporary(they are called temporary as results are not stored anywhere which gets lost as soon as a query’s execution is completed) named result sets, derived from a simple query that can be referenced within a single SELECT, INSERT, UPDATE, DELETE or MERGE statement. CTE’s can include references to itself which are recursive common table expressions.

CTE syntax

[WITH <common_table_expression> [ ,…n ] ] <common_table_expression>::= expression_name [ ( column_name [ ,…n ] ) ] AS ( CTE_query_definition )

Reference :- https://ift.tt/385pUMs

Meanings 

expression_name

A  valid identifier for the common table expression whose name must be unique to other common table expressions defined in the same WITH <common_table_expression> clause

column_name

This specifies the name of the column in the common table expression where no duplicate names within a single CTE definition are allowed. 

CTE_query_definition

It is the SELECT statement where we are defining our result set. If there is more than one CTE_query_definition, the query definitions must be joined by any of these set operators: UNION ALL, UNION, EXCEPT, or INTERSECT.

Example

In this example, let’s consider a table “students” which contain the following data:-

IdNameEmailSubject1Riyariya@beetechnical.comComputer2Amishaamisha@beetechnical.comphysics3Priyapriya@beetechnical.comhistory4Kiarakaira@beetechnical.comcomputer5Minimini@beetechnical.comEnglish6Rajuraju@beetechnical.comcomputer7Akashakash@beetechnical.comphysics8Rajeshrajesh@beetechnical.comcomputer

Query:

WITH students_of_computer AS (SELECT * FROM students WHERE subject = ‘computer’) SELECT student_name, email, subject FROM students_of_computer;

In this example, the CTE name is students_of_computer where the subquery that defines the CTE returns the three columns student name, email, and subject. So at the end of the result, the CTE students_of_computer will return all the students who have taken the computer subject.

After defining the CTE students_of_computer, we have referenced it in the SELECT statement to get the details of students who have computers as their subject.

Output:

IdNameEmailSubject1Riyariya@beetechnical.comComputer4Kiarakaira@beetechnical.comcomputer6Rajuraju@beetechnical.comcomputer8Rajeshrajesh@beetechnical.comcomputer

The result returns only those student’s information who have taken computer as their subject.

Types of CTE in SQL 

SQL has two types of CTE (Common Table Expressions) They are as follows:-

Recursive CTE

Non-Recursive CTE

Recursive CTE

CTE that references itself within that CTE is called recursive CTE(a concept is based on recursion) that is very helpful while working with hierarchical data. In simple words, CTE is queries that call itself.

Syntax:

WITH cte_name (column_list) AS ( — Anchor member initial_query UNION ALL — Recursive member that references cte_name recursive_query ) -- references CTE name SELECT * FROM   cte_name

Example

To understand how recursive CTE works in SQL, let us take the below example which will generate a series of the first 4 odd numbers:

WITH odd_no_cte (id, n) AS ( SELECT 1, 1 UNION ALL SELECT id+1, n+2 from odd_no_cte where id <= 4 ) SELECT * FROM odd_no_cte;

Where the output of the recursive CTE will be:-

id no11233547

Non- recursive CTE

Non-recursive CTE is just as its name sounds.CTE that doesn’t reference itself within that CTE is called non-recursive CTE and it is more simple and easy to understand as it doesn’t use recursion.

Conclusion

So in the end, we can conclude that the CTE in SQL can be useful for the following reasons;-

For easy readability of code

Presence of recursive queries that calls themselves makes working on hierarchical data easy

Code maintainability get easier with CTE

CTE act as substitution for a view

What are the Aggregate Functions in SQL with Examples?

If you have worked with SQL databases then you might be familiar with these functions. In this post, we will try to explain the aggregate functions in SQL using some basics examples.

Aggregate Functions in Mathematics

Mathematically an aggregate function is a computation of a range of values resulting in a single value that expresses the significance of the accumulated data that it is derived from. These functions are used for the derivation of descriptive statistics.

What is the aggregate function in SQL? 

There are lots of functions in SQL and aggregate functions are one of them. 

Aggregate functions are used in database management to group the values of multiple rows and return only a single scalar value by performing calculations on those sets of values.

Aggregate functions are often used with the GROUP BY and HAVING clauses of the SELECT statement where null values are ignored (except for COUNT(*))

Various Aggregate Functions of SQL

All aggregate functions are deterministic i.e returning the same value every time whenever called with a specific set of input values.

Some most common aggregate functions provided by SQL are:-

1) Count()

2) Sum()

3) Avg()

4) Min()

5) Max()

SQL aggregate functions syntax

The syntax of calling an aggregate function is as follows:-

aggregate_function (DISTINCT | ALL expression)

Where the meanings are:-

1.) aggregate_function:- This specifies the name of the aggregate function to be used which can be count(), min(),sum() , etc.

2.) DISTINCT | ALL expression:- Distinct modifier is used to ignore duplicate values and only consider the unique/distinct values. | is an OR symbol. ALL modifier is used for considering all the values in the calculation.

Note:- All modifier is used by default when no modifier is defined explicitly.

3.) expression:- It can be any expression of multiple columns with arithmetic operators.

Examples of SQL aggregate function 

Let’s understand the Aggregate Functions of SQL that we mentioned above with the help examples.

1. COUNT FUNCTION  Example

COUNT is an SQL aggregate function that counts the total number of values(both numeric and non-numeric data types) present and returns the values according to the criteria given.

Syntax

For example, to find the total number of students who are less than 15 years of age, we can use the given query. 

SELECT COUNT(*) FROM students WHERE age < 15;

Points to remember about COUNT function

COUNT helps to verify results very simply.

COUNT(1) has the same effect as COUNT(*).

COUNT (*) also considers Nulls and duplicates

If a column name of the table is used instead of *. Unlike COUNT(*), the variation COUNT(column_name) will not count NULL values in that column.

2. SUM FUNCTION  Example

SUM is an SQL aggregate function used to find out the sum of all the values(only numeric data types) in the selected column, where the column name is an argument and the total sum of all the values in that column is returned as result.

Syntax

For example, The query below selects the sum of the marks column from the Marks_student dataset:

SELECT SUM(marks) FROM marks_student;

Points to remember about SUM function

The calculation works only vertically i.e only for a column and if you want to calculate across rows then simple arithmetic can be used.

SUM doesn’t considers Nulls as SUM treats NULL as zero

SUM function works on numeric fields only.

3. AVG FUNCTION example

AVG  is an SQL aggregate function that is used to find out the average of a selected group of values(only used on numerical columns & Null values are ignored.)

Syntax

For example, we can use the given query to find the average salary for workers who have less than 3 years of experience.

SELECT AVG(salary) FROM workers WHERE experience < 3;

4.Min Aggregate Function

MIN is an SQL aggregate function that is used to return the lowest/minimum value of all selected values(both numeric and non-numeric data types) in a specified column of a table. MIN functions ignore NULL values.

Syntax

For example, we can use the given query to find the smallest/minimum value of the marks column from the table named subjects.

SELECT MIN(marks) FROM subjects;

5. Max Aggregate Function

MAX is an SQL aggregate function that does the opposite of the MIN function.MAX function is used to return the largest/minimum value of all selected values(both numeric and non-numeric data types) in a specified column of a table. MAX functions ignore NULL values.

Syntax

For example, we can use the given query to find the largest/maximum value of the marks column from the table named subjects.

SELECT MIN(marks) FROM subjects;

Top 30 Interview Questions on Rest Web Services with Answers

REST API is becoming more concrete as the internet world progressing. It comes up with a big list of benefits for the market industries. Since RESTful web services do not follow any prescribed standard except HTTP, it becomes essential to build API with best practices to enhance client adoption and ease development. In this blog, we will discuss the top 30 Interview Questions on Rest Web Services that are often asked by interviewers. Let’s learn!

1.What do you know about REST Web Services? 

Representation State Transfer (REST) is defined as stateless client-server architecture used for the development of applications. It leverages the benefit of the HTTP method and Protocols for defining actions. Though there is no particular protocol to be used, we use HTTP/HTTPS in most cases. 

On comparing with SOAP web services, REST API web services are light-weighted and do not follow any specific standard. We can make use of JSON, text, XML, or other data for response or request. 

2. Tell us some key characteristics of REST?

Well, the key characteristics of REST are –

Since REST is stateless, hence there is no state or session for Server

The server could restart between the two calls whenever the data is passed over it with a Well-applied REST API

POST methods are mostly used by Web service to make operations, however, REST makes use of GET for accessing resources.

3. What are the benefits of using REST web services?

Some of the big advantages of using REST API are-

The learning curve is quite simple and easy as it works on HTTP/HTTPS protocol

Supporting several technologies for transferring data including JSON, XML, text, images, etc

REST can be easily tested on any browsers

There is no contract defined between the client and the server, so their installation could be loosely coupled.

REST – lightweight protocol

4. What do you mean by “Resource” in REST?

REST architecture considers every content part as its resource. Now, resources could be HTML pages, text files, videos, images, or business data. 

Access to resources is provided by REST Server and it’s REST Client that accesses & makes modifications to these resources. Each resource in REST is identified by global IDs /URIs.

5. What is the most popular way of representing resource in REST?

Different representations are used by REST to define resources like XML, JSON, and text. The most popular representation of resources is – JSON and XML.

6. Name the most commonly used HTTP methods that are supported by REST?

GET, PUT, POST, DELETE, OPTIONS, HEAD.

7. What is the function of GET and POST?

Well, GET requests to resource at the request URL. The request body shouldn’t contain as it will be discarded. Maybe it is cached on the server or locally. 

Whereas, POST submits information to services for processing as it must return new or modified resources. 

8. Is there any disadvantage of REST web services?

In each request, web services require extra information and then to be interpreted to get the client’s state. This happens when client interactions needed to be taken care of. This is included in the cons of staleness in RESTful web services.

9. How you will define idempotent operation?

Idempotent operations state that results will always remain the same. It doesn’t matter how many times operations are involved. 

10. Which type of web services are counted amongst the idempotent operation?

PUT and DELETE

11. What Web services methods are read-only?

GET operations are safe and read-only

12. How you will tell the difference between PUT and POST operations?

Generally, both are the same but the difference lies in their result. While PUT operation is idempotent and shows no change; POST operations come up with different results. 

13. What is the purpose of the OPTIONS method?

OPTIONS list down all the supported operations in RESTful web services. Plus, it must be a read-only format. 

14. Which HTTP response header shows the date & time of resources when it was modified last?

Last-Modified Header

15. Which HTTP response header gives you control over caching?

Cache-Control gives you control over caching. 

16. Tell us about the Cache-control header?

A cache control header helps you to attain cache ability. There is a brief description of several cache-control headers like –

Public – Those resources marked public are cached by any intermediate component between the server and the client. 

Private – These resources are cached only by the client

No cache– This explains a specific resource cannot be cached and that’s why the whole process is stopped. 

17. Name the header of the HTTP response that sets expiration time and date of caching?

Expires header

18. We can set a time limit for caching. Right? So, which directives of Cache-control we will use in the HTTP response?

The max-age directive, we would be used. This says caching is valid up to max-age (in seconds). After this, the client has to provide another request. 

19. What are some best practices for caching that good to be followed?

Always keep static content like CSS, images, JavaScript cacheable. This includes an expiration date of two or three days. So, don’t keep the expiry date too high. If you are using dynamic content, then it must be cached only for a few hours. 

20. What do you understand by JAX-RS?

JAX-RS is a Java API for RESTful web service. Undoubtedly, the most popular among java programming language that is widely supporting web Restful web services. Here are some implementations of JAX-RS –

RESTEasy

Jersey

Play

Apache CFX

Jersey is most popular amongst these mentioned. 

21. Tell us something about JAX-WS?

JAX-WS again are libraries just like JAX-RS which are used for communicating with Java in several ways. JAX-WS is a library that we can use for SOAP communication in JAVA. 

22. What is the purpose of showing the HTTP Status Code?

HTTP status codes are set predefined codes that describe the task done at the server. For instance, HTTP Status 404 states – your requested resources are not available on the server. 

23. What about code 200 status code?

Whenever this code appears on the screen, it means OK showing success. 

24. We often see code Error 400. What does it mean?

400 say BAD REQUEST. It means you have added invalid inputs that are not present on the server. It could be missing data or a validation error. 

25. Can we make use of GET request despite PUT for creating a resource?

Well, PUT as well as POST methods are only used for creating the resource. However, GET is just used for requesting the resource. So, the answer is No. 

26. What are the major challenges that are often faced while doing API Testing?

There are major challenges like – Call sequencing, parameter selection, Output verification & validation, Parameter combination. Plus, the major challenge is to provide input values since the GUI is not available. 

27. How SOAP is different from REST API?

SOAP (simple object access protocol) works with XML format only whereas REST API is possessed with varied options like HTML, XML, JSON, plain text, etc. The most refereed format that is used for data transferring is JSON in REST API. 

28. What kind of bug you can found during API Testing?

API testing helps us to get many types of bugs that are-

Missing or duplicate functionality

Security

Stress

Performance

Multi-thread issue

Incompatible error handling

Unused flags

Improper errors

Reliability issues

29. Name the core components of the HTTP response?

HTTP Version, Status/Response Code, Response Header & Response Body.

30. Can you tell me about the three main tools that are available for testing web services?

Yes, the three tools that help test SOAP and RESTful web services are –

Poster for Firefox browser

SOAP UI tool

The Postman extension for Chrome

We hope you are clear with the most important questions that are often asked in the interviews. Learn these thoroughly and answer confidently. You will certainly get your job. All the best, do well!

When to use NoSQL vs SQL database

Both the SQL database and NoSQL database stores data but each of the databases stores data differently. However, People often get confused between when to use NoSQL vs SQL database databases whereas choosing which databases to use when totally depends on the type of information to be stored, None of them is a replacement for each other rather they are just an option for the user to choose among, even they can choose both depending on their requirements.

This article will cover up what SQL and NoSQL are, the differences between NoSQL and SQL databases, and when you should use NoSQL databases and SQL databases.

What is SQL database?

source:- https://ift.tt/3zm0aH1

SQL ( Structured Query Language)is a domain-specific language used to manage and manipulate data in a relational database management system (RDBMS). This relational database stores data in the form of tables, SQL databases such as PostgreSQL and MySQL are some famous SQL databases.

What is NoSQL?

source:- https://ift.tt/3eKPOsx

.wp-duotone-filter-60f8dd1b8e1a1 img { filter: url( #wp-duotone-filter-60f8dd1b8e1a1 ); }

NoSQL (non SQL, Not only SQL) is a non-relational database so they are not bound to store data only in the tabular form like in SQL, they can store unstructured and unrelated data in JSON documents, Graphs, and key values also.MongoDB is one of the popular NoSQL databases.

Quick Comparison between NoSQL and SQL Database

Now that we are quite familiar with the differences between SQL and NoSQL, let’s see where you should use them.

When to use SQL?

If you are working with complex queries

When you are working with highly structured data where they doesn’t change very frequently

When you have requirement for Multi-Record ACID Transactions support

It is the ideal choice for high transaction application as it ensures stability ,consistency and data integrity

For building custom dashboards, SQL stores and fetches data from the database very quickly.

When to use NoSQL?

NoSQL is the best option if you are dealing with a huge volume of structured, unrelated and unstructured data

When you are dealing with applications with a highly flexible schema and there is a constant need of adding new features and functions

When data consistency and 100% data integrity is not the goal and ACID support is not needed

NoSQL is an ideal option for big data applications, real-time analytics, etc.

When scalability and availability is the top priority

Conclusion

Finally, the decision of choosing SQL and NoSQL depends totally on an individual, but in this article, we have given you a brief idea about the scenarios when you can choose SQL and when you can choose NoSQL.Although both have their own pros and cons.SQL is the best option while dealing with established structured data with fixed schemas and NoSQL is the best option while dealing with unstructured and unrelated data with flexible schemas and a high need for scalability and flexibility.

Brief intro about firebase google and its features

Firebase Google or Firebase

Firebase is a mobile and web app application development platform that was originally an independent company founded in 2011 and later in 2014, Google acquired this Firebase platform and the name was appended firebase google.

In our today’s article, you will come to know everything related to firebase that will give you an overall essential idea related to Firebase.

What is Firebase?

Have you ever thought of building your own apps? if yes then you have definately heard about Firebase. Firebase is a Backend-as-a-Service(Baas) both for mobile and web-based applications that provides a variety of tools and services for the developer that helps them to build, test, and manage their apps perfectly.

Firebase is a Baas service so when you connect your app with Firebase further you don’t have to bother much about the management of the backend database of your app. You just have to plug Firebase into your app via dedicated APIs for each separate service. Firebase can integrate with platforms like Android, IOS, Web, and Unity.

Firebase is a Realtime Database, When you connect Firebase to your app, you’re connecting it through a WebSocket(much faster than HTTP), whatever data is saved by you or your client is updated automatically without a delay.

Features provided by Firebase

Database Management

Hosting

Authentication

File storage

Cloud Messaging

Remote Config

Machine Learning

Test Lab

Crash Reporting

How to use firebase with android?

We have already discussed that firebase can integrate with the Android Platform for developing high-quality apps. All you have to do is to connect your app with Firebase via dedicated APIs for each separate service.

There are some Prerequisites for adding Firebase to your Android project. Let’s have a look at it.

Install or update Android Studio latest version.

Now make sure that the project meets these requirements:

Targets API level 16 (Jelly Bean) or later

Uses Gradle 4.1 or later

Uses Jetpack (AndroidX),

Set up your Android device or use an emulator to run your app. Note that Firebase SDKs with a dependency on Google Play services require the device or emulator to have Google Play services installed.

Sign into Firebase using your Google account.

After that, you can integrate Firebase services with your app directly from Android Studio using the Assistant window

Source:- firebase android setup, Android developers

For getting more familiar with Firebase in Android you can check their main site.

What is Firebase Database?

Firebase has 2 types of databases

Realtime Database

Cloud Firestore

The Firebase has 2 types of databases one is Realtime Database and another one is Cloud Firestore. Both are NoSQL Databases. Realtime Database that allows you to store your data securely and at a high speed on Google cloud servers which gets synchronized in real-time across all clients sharing the same database with a little bit of coding effort by the developer.

Firebase Realtime Database

Realtime Database provides data persistence by storing data locally so that the data can be accessed even when a device is offline and the local data gets automatically synchronized after the connectivity is re-established and gets merged with the remote data.

Firebase stores and sync data using NoSQL cloud databases for storing data in real-time.NoSQL stores data in the form of a JSON(JavaScript Object Notation )object as JSON format is both lightweight and easy for understanding. whenever there will be a change in the database, it will get reflected all the other devices connected to it in real-time

How the data is stored using JSON? Well the entire database in Firebase has multiple JSON objects and those are structured in the form of a big JSON tree with multiple nodes, so you have to manage the json structure in such a way that the data are easy to access way without the need to the nesting of child nodes

A simple example of JSON format:-

{ "name" : "beetechnical" }

Firebase Realtime Database

Cloud Firestore stores simple data as a collection of documents which is quite similar to JSON. It also provides online support like in Realtime Database . Cloud firesdtore gives you advanced writes and reactions operations. In the matter of Reliability and Performance Cloud Firestore is better as it provides multi-region solution for scaling automatically. For providing strong realibility and scalability data is shared across multiple data centers in separate Note :- Cloud Firestore is Firebase's newest database. It builds on the successes of the Realtime Database with a new, more intuitive data model. Cloud Firestore also features richer, faster queries and scales further than the Realtime Database. If you are confuse regarding which one to choose then check their main site.

What is firebase used for?

We already know that Firebase is used as a Realtime Database that helps with the backend development of your app in Android, iOS, or web, along with that firebase is also used for some other reasons too i.e. they provide some other good functionalities which are beneficial to your app that makes your app grow much faster. Let’s look upon 4 of the uses of the Firebase:-

1.) Analytics

2.) Authentication

3.) Cloud Messaging

4.) Remote Config

Is Firebase Hosting Free?

Firebase Hosting is free but may have usage limits on some of the features. By default, it provides an SSL certificate and offers an Amazing speed across multiple geographic locations. Their pricing tagline itself says ” start for free, then pay as you go”. Check their pricing plans here.

What is Firebase Authentication?

Firebase Authentication will provide you backend services, easy-to-use SDKs, and ready-made UI libraries for authenticating users to your app. Authentication is done using passwords, phone numbers, popular federated identity providers like Google, Facebook, and Twitter.

Lets discuss How does authentication work:-

When a user gets sign in to your app they give their credentials such as the user’s email address and password, or an OAuth token from a federated identity provider and you get the authentication credentials from the user, after that these credentials are passed to the Firebase Authentication SDK and Firebase backend services verify those credentials and return a response back to the client.

After that a successful sign-in takes place and you can access the user’s basic profile information, control the user’s access to data stored in other Firebase products. The provided authentication token by the user can be used by you to verify the identity of users in your own backend services.

Azure Data Lake Storage(ADLS) Gen1 vs Gen2 Complete Guide 2021

Azure Data Lake Storage or short name Data Lake is a system or repository of a huge quantity of data in a structured or unstructured form that is stored in its natural format(i.e object blobs or files). Data lakes handle the three Vs of big data (Volume, Velocity, and Variety). Let’s dig deeper and understand all the topics related to Azure data lake. Hope you will find it helpful for sure.

What is Azure data lake storage?

It is a part of the Microsoft Azure public cloud platform, which is a cloud platform that supports big data storage and analytics of any kind and size.

Source :- https://ift.tt/1rRy2co

The data lake storage is the storage of information solutions that has specifically been designed for the analytics of big data. Its working is quite simple. Each data lake service underneath always has a container. That container is very often called a file system and just like any file system it has folders and files within it which is fully scalable and secure that supports HDFS semantics while working with the Apache Hadoop ecosystem. On each data lake, you can actually have multiple containers, multiple file systems containing any structure of files and folders that you wish to have.

Some notable features of Azure data lake storage are as follows

Infinite size of data can be stored in a single repository.

Both structured and unstructured data in their natural formats can be stored

There is high availability, durability, and reliability.

There are 2 types of Azure data lake storage (ADLs) ADLS Gen1 and ADLS Gen2. Let’s try to undetstand each of them in details.

Azure Data Lake Storage Gen1 & Gen2

source :- https://ift.tt/1rRy2co

Earlier Gen1 was generally used but now Gen2 is mostly used and it is also reported that on Feb 29, 2024, Gen1 will be retired, so anyone using ADLS Gen1 has to migrate to Gen2 by that date.

Data Lake Storage Gen1 can be accessed from Hadoop using the WebHDFS-compatible REST APIs. It has all enterprise-grade capabilities such as security, manageability, scalability, reliability, and availability.

Data Lake Storage from Gen2 is designed for big data analytics which means there is something called azure blob file system or ABFS which is encrypted. This file system is compatible, allowing many of the existing solutions in the market to connect with no hustle.

All the systems have almost no issues connecting to data-lake. Out of the box, just a few lines of the code recommendation and you are ready to use it. But additionally, one thing to highlight is the multi-protocol access. With the help of this access, you will not only have the azure blob file system but you will also be able to access the windows azure storage blob [WASB].

Data Lake is an information lake service that is given by Microsoft azure. There are two components to the azure data lake. The first we called the data lake analytics and the second is known as the data lake store

Quick Comparison Between Azure Data Lake Gen1 vs Azure Data Lake Gen2

In the azure data lake storage Gen1, you can store literally any amount of data of any size for any amount of time. So basically you will run analytic jobs using data lake analytics on the data stored in the data lake store.Whereas talking about Azure data lake storage gen2, this advanced version will have both the options for storage that is the file system storage as well as the object system storage.According to the Azure data lake storage gen1, the user will be able to store the data in the form of file storage which is separated into blocks giving you performance & security. This can be dependent on the Azure data lake storage hierarchyWhereas Gen2 provides you with safety as well as healthy and smooth performance. When we talk about object storage, it is there for scalability.Gen1 does not supports Hot/Cold and Redundant storageWhereas Gen2 supports Hot/Cold and Redundant storage

How to create Azure data lake storage gen2?

Source :- https://ift.tt/1rRy2co

After clearing all the doubts the question arises that How to access ADLS gen2?

All you require to have is an access key to the ADLS account

You will get the access key from the storage account of azure

You will go to the Data bricks workspace and create the secret scope.

After this process, you have to connect the secret scope and the access key.

These two that is the access key along with the secret scope will be used to create your account for storage. You will quickly be able to locate your Data Lake account.

Azure data lake storage gen2 vs blob storage

Azure data lake storage and Azure Blob storage have many variations among them. Let us have a glance at the main and important differences:

Data Lake gen 2 allows the granular access control on a higher level as compared to the blob storage because it supports the ACL permissions.

ADLS is a hierarchical file system that possesses a hierarchical namespace. If we have a look at the blob storage, we will find a flat namespace. This is a dig in the performance of blob storage when we are talking about big data analytics.

ADLS gen2 is Hadoop friendly and they can use the data which is available in storage while the blob storage is not compatible with it

Azure data lake storage Power BI

source :- https://ift.tt/3vtCf6e

To access the azure data lake gen2 power bi, you have to first launch power bi on the desktop of your system. After this, you will have to select the option of “get data” followed by “select more” in the home tab. Go through the following steps mentioned below.

Azure followed by the azure data lake store gen2 followed by connecting.

After following these you can connect to DataLake gen2 power bi

Here you again have two options to select from. Either you can use the file system or else the common data folder. The choice depends upon the user.

Azure data lake storage architecture

An azure data lake is fully based on the Apache YARN which itself is a cloud management tool. Build on apache Hadoop, this cloud-based solution has no need for the hardware that is provided by its user to get installed. ADLS security assures full safety and it is designed in such a way that it possesses low latency.

Azure data lake storage python has been released by Microsoft as a better and second version of python linked with the it. It will provide you with a hierarchical namespace, capabilities of blob storage, and atomic operations.

Azure data lake gen1 pricing

Talking about the pricing you can pay according to the storage.

Eg:

for the usage of the first 100 TB, you will have to pay an amount of Rs.2.8098 per GB.

second 100TB to 1000 TB, you will pay Rs.2.7378 per GB.

and third 1000 TB to 5000 TB the user will have to pay an amount of Rs.2.6657 per GB.

If you find it costly, you can also go with the monthly packages where you will have to pay with a discount of almost up to 33%.

Azure data lake storage gen 2 limits or when we talk about the storage capacity, it is unlimited. It is the most productive way of storage of data.

Azure data lake storage gen 2 disaster recovery

source :- https://ift.tt/1rRy2co

Data Lake Gn 2 disaster recovery can be a bit hectic and time-consuming. It has certain limitations which lead to fail sometimes. You can easily check out their link on their site to avoid all these failovers.

Azure data lake storage monitoring is the metrics provided by the gen2 beneath the storage account present in the azure monitor.

Conclusion

After knowing quite a lot about Azure data lake storage , we can come into a conclusion that it is one of the best place to store all your data undoubtably.It provides high storage of data in less cost with lots of facilities that you should definately opt for .

Also if you are using Gen1 or planning to use Gen1 then I will definitely suggest you shift or choose Gen1 as Gen1 is going to retire soon in 2024.

How to setup Azure DevOps pipeline Step by Step Guide 2021

Azure which is actually known as Microsoft Azure was created by Microsoft. It is a Cloud computing service created for building, testing, deploying, and managing applications.

Software development(Dev) and IT operations (Ops) are combined together with the help of a set of practices called DevOps. 

 The path to building a pipeline is with Azure DevOps with the help of the feature called Azure Pipelines  In the Microsoft realm.

Azure DevOps Pipeline

We can build and test our code project automatically with the help of Azure Pipeline which is a cloud service

 Developers, DevOps teams, or anyone else can produce and deploy reliable code.

There are lots of things the Azure pipeline can do starting from continuous integration (CI) and continuous delivery (CD) to automatically run builds, perform tests, and shipping code to any target.

I am writing this article to describe how to set up the Azure DevOps pipeline for those people who have never heard of the pipeline or Azure DevOps before or have never built a pipeline with Azure DevOps.

 Setup Azure DevOps pipeline

First we have to create an Azure DevOps Organization

Visit the Microsoft Azure website and Sign in 

2. Click on + Create a resource

  3.Search for DevOps in the Search box and select Azure DevOps and it will open the Azure DevOps as following:-

 Next, click the My Azure DevOps Organizations option and give your Azure account’s details and you will be taken to the page where you can create a new organization(I will give the name sulagnamukherjee). Once you are there, click the blue color option of Create a new organization button.

5. Next, you will be taken to a page where you have to provide a name for the organization. You can check the Azure DevOps organization naming conventions and click Continue.

You have successfully created your Azure DevOps organization 

Next, Create an Azure DevOps Project

Now you have to create a project. A project that you will create will be a container for the pipeline that you will set up next. 

Follow the given steps for creating Azure DevOps Project

Give the name for your project in the Project name field on the project creation page, provide a. For this project, I will give the name of the project as Demo_project and click the + Create Project button to Confirm the creation of the project.

We will leave the Visibility set to Private so that the project isn’t exposed to the Internet.

Now we are done creating the Azure DevOps workspace that includes the project  & organization. The Azure DevOps organization called sulagnamukherjee and a project inside of that organization called Demo_project has been created.

Now, we have to build an Azure DevOps Build Pipeline

Now we are ready to create the pipeline inside the organization and project set up, this pipeline will help us to create builds for performing different tasks like compiling code, bringing in dependencies etc. Check the following steps to create the pipeline:-

From the Dashboard on the left side select Pipelines

Click on the Create pipeline button.     

 Click on the “Github” option

4.Now we have to select the repository that you want to select.          

5. Approve and install it 

6. Configure your pipeline using any of them you want according to your requirement

7. Review your pipeline 

8. Save and run it

9.         Now you are done setting up the pipeline

10. Go and check the pipelines and you will find your pipelines have been set up.

11. Click on the pipeline to view and run it.

Why choose our data center for your business? If you want answers to all these questions, you will get all the answers in this article. Keep reading till the end.

Data Center Strategy

Today, businesses prefer data centers for better data management. Investing in a reputable data center boosts the business sales. There are numerous components for good business performance that are storage management, servers, routers, telecommunication equipment to store, send, and receive data. More reasons for choosing data centers are security issues, fire, disasters, etc. So, considering all these factors, businesses need data centers to rely on.

What if you don’t want to invest in your own data center, reason might be anything. The reason might be cost, management, man power, etc. Let us first see different reasons why it is difficult to establish your own data center, and then why to choose us?

Cost of Data Center

The total cost of a rack in a data center is approximately $100K for the lifetime. The cost breaks into different categories like Power Equipment, Space, Project Management, Racks, Service, Electricity, Engineering Installation, etc. Don’t worry, we will not charge you this much. We charge according to the types of services we are offering you. And you choose the services you want from us.

Data Center Server selection

Data Center services provide servers to businesses to optimize power usage for better data management. Servers provide storage systems for storing data of the business.

The best part is you are not charged according to the hour, but as per the data taking disk space, and the bandwidth website is using.

Does location of Data centers matter?

Of course, the location of data centers have a huge impact on the working of data centers. Before investing in any data centers you must take care of the following points, we have discussed below –

Disaster Avoidance

The threat caused by Natural Disasters like Earthquakes, hurricanes, floods, lightning storms, can cause damage to data centers. Before installing the infrastructure, it is important to know the environmental stats of the place. Otherwise, it can cost big damage to the business. An area with low chances of natural disasters should be chosen. So, site selection is important. And we have chosen the right location for our data center. And that is California.

Availability of Power

Data centers need huge power to operate a data center. In the US, data centers generally consume power of 75000 watt. Making the data centers efficient is the demand of the IT industry. Electricity cost of a data center is the second big amount in the expenses of data centers. At the site place, electricity should be available easily at a cheap rate. For the electricity purpose, water availability should also be kept in the list.

Establishing data centers promote employment and require man power for the construction. At the data center site, there is a need for site engineers, IT, and electrical engineers. The local skill availability should be checked while planning for the data center.

Climatic conditions

We have already talked about natural disasters, climatic conditions also affect the working of data centers. Proper network facilities are important for the data centers. Data centers need cool temperature and humidity, required for cooling data centers. So, they should be established at cooler locations like Scandinavian countries in Europe or the USA.

Tax Structure

Political conditions of the location also impact the overall business of the data center. Corporate tax structure varies from state to countries. Since, the establishment cost of data centers are very high, companies want to reduce the tax payments. The companies should look for the location which offers lower taxes.

If you compare our services with other companies. Then you will find out how excellent services we are providing at an affordable price. Do you know at what price other companies are providing dedicated servers? Let us see some price plans –

If we talk about Hostinger, its price of dedicated servers starts from $120 per month. The price of dedicated servers by Bluehost, starts from $79 per month. The Liquid Web price also starts from $199 per month.Even Hostgator charges $90 per month. From this, you can see we are charging very less. And providing services equivalent to them at less price. I do not think you need any more reason to choose others.

Our services out performs as compared to others at lower prices. Either in terms of network speed, security, team support, and more.

Is choosing a dedicated hosting correct for your business?

It is the big decision as the cost is higher compared to shared hosting or VPS hosting. But we have already seen, dedicated servers are far better than others. Mostly the companies which chose dedicated hosting are mid-sized to large. But, some small companies also prefer dedicated hosting for security purposes. Typically, this type of hosting works best for companies who need high security, or get large traffic. The startups do not need this hosting but may upgrade later when business grows. Remember your business needs right hosting to survive. Unlike shared services, it needs high maintenance cost. Today, dedicated servers are the most powerful hosting machines in the market.

With the rise in security threats it is not possible to have a solution for everything. But we take all security measurements to protect the data from any kind of threat.

Always do research before choosing a hosting service. It is important to see long term benefits. Because it is going to have a big impact on your business in the present and going to impact the future. Take your time and then make wise decisions. Then chose the correct hosting for your website.

Is the cost of dedicated servers high?

Yes, the cost of dedicated servers are high as compared to other servers. Because dedicated servers are specifically designed for you. Have a plan beforehand, it will help you to make decisions for long term benefits. Take a clear look at your website. Measure its efficiency and effectiveness and then decide to shift your services. The cost of other servers like LINUX servers, shared servers, are lower than dedicated servers. So, it completely depends upon your budget, business requirements to decide which type of server is best for you. We have all types of servers, varying in range too from cheapest dedicated servers to business plan dedicated servers.

Consult with Professionals

If you are not able to take any decision, you can consult a professional. Who can have a deeper look at your website, and help you make the decision. A professional can analyze the needs of your business. He can tell a lot about your website’s future, do you need to scale it right now or not. So, he will give the right guidance to your thoughts.

Conclusion

The conclusion is the decision of  deploying a server majorly depends upon business requirements. If the business is small or medium sized, you can get a good deal of cheap dedicated servers. But if the business is well established, you can go for big dedicated servers available at a reasonable price. Therefore, it is worth it to deploy a dedicated server on the low price.

All You Need To Know About Azure Functions!

Serverless computing is the choice of the world, and Microsoft Azure Function makes this possible by delivering event-driven cloud computing & configuring application development with it. But how exactly Azure does this? What are the advantages of using it? What would be the cost estimation? Know all your answers on this blog.

What is Microsoft Azure?

Microsoft Azure generally referred to as Azure, is an ever-expanding set of cloud computing services help organization to match business challenges. It gives freedom to build, test, deploy, and manage applications using your favorite frameworks and tools via data centers managed by Microsoft.

A Brief on Azure Functions

Azure Functions is the serverless computing services designed to simplify and accelerate application development. These functions offer the ability to run small codes, functions in an extremely scalable, flexible & cost-effective manner. Not to doubt, Azure combines the best world of web services and schedule software as it ultimate in infrastructure abstraction. Also, it removes any concerns that are related to operating systems and underlying servers.

Azure Pricing Details

The pricing of Azure functions depends upon the execution time and total executions. This includes a monthly free grant of one million requests & 4,00,000 GBs of resource consumption in a month.

Execution Time:  $0.000016/GB-s

Total Executions: $0.20 per million executions

On buying, Azure Premium plan, users can avail of enhanced performance. It is billed based on GB-s and vCPU-s.

vCPU Duration – $0.173 vCPU/hour

Memory Duration – $0.0123 GB/hour

Advantages

Since Azure functions offer you cloud services, it comes up with a big list of advantages that are as follows –

Pay as per your model– Azure Functions comes in the “Pay as you go model” which means users have to pay only for what they are using. The cost of the Azure function is based on the executions/month (mentioned above).

Support different languages – The best part of Azure function – it supports a variety of languages like Python, C#, Java, F#, and many more.

Easily integrate with other Azure Services– Azure functions can also integrate with other services of Azure like Event Hubs, Azure Service Bus, Notification Hubs, Event Grids, and many more without any inconvenience.

Trigger-based executions – Azure functions can easily be executed based on configuration triggers. This supports various triggers like Queue Trigger, Event Hub Trigger, HTTP triggers, and more. It runs on-demand as it’s a trigger-based service.

When to Use Azure Functions?

 Azure functions are like logic applications that are “event-driven”. It means they run based on configured and associated events, or “triggers.” For instance, an Azure Function can be trigger by an event in DMS (document management system), running process once every 24 hours, or when a new document is uploaded to the SharePoint library.

Azure Functions also respond to Azure-specific events, such as notifications arrive in Message Queue, or the addition of an image to a Storage Blob.

Here are the typical scenarios where we make use of Azure Functions –

SaaS event processing

Azure service event processing

Serverless mobile backends

Timer-based processing

Real-time bot messaging

Real-time stream processing

Serverless web application architectures

Cost Estimation for Azure Functions

Two hosting models for functions are provided by Azure. The first one is named Consumption plan which is the canonical way of Function use. This plan offers the pay-per-use model. However, there are a few caveats associated with it –

Functions running on the consumption plan have a time limitation of 5 minutes. It means those function that runs more than 5 minutes, the runtime may abruptly kill the function & data not persisted would be lost. Though you can extend the time to 10 minutes, yet by default 5 minutes is set.

Limited Memory Usage – 1.5 GB which is shared among the functions that are present within the Function App.

Scaling is automatically handled and it based on the back pressure of triggers. The unit of scale is named as Function app. When the function app gets scaled, then additional instances were provisioned. Better understand with an example, if function triggered by a new message in the Azure Service Bus Queue, the runtime will monitor the age of oldest message and depth of queue to check if there are additional instances should be provisioned or not. For each trigger type, there is unique scaling.

After idling for a period, functions “turn off” and it can also incur a startup cost in respect of performance. The performance penalty can be reduced.

The pricing model for the consumption plan is solely dependent upon use, not provisioning. The combination of GB-s and number of execution is the cost of function as mentioned in pricing details.

Here, is the formula for calculating GB-s is

 GB-s = (number of executions) x (execution duration in seconds) x (amount of RAM used in GB).

App Service Plan

App Service plan is the other hosting model where you can select the VM configuration to be provisioned. It’s the same plan, as Azure Web Apps that are being used for other PaaS offerings. The amount of RAM and the number of cores is static within the configuration, so choose the correct configuration as the price would be directly affected.

Which Plan is good to pick?

Most users choose the consumption plan as it’s a default choice. However, you can also go with App Service plan if-

Your functions consuming more than 1.5 GB memory

You already have an underused App Service plan that  supports Function app

The startup performance penalty required to be eliminated

Your Azure function needs to actively run for more than 10 minutes

There is a need to configure network options for security or accessing to secure resources (like IP whitelisting or VNET integration)

The Bottom Line

Azure functions make the application development simple and quick with its ultimate capabilities. Cloud computing improved things a bit, but there are many changes to be looked upon.

With Azure Functions serverless architecture, it’s quite possible to stop worrying about the infrastructure considerations that you faced previously. Now, just focus on creating and uploading proper code. The highlight of Azure functions is – you can write the code in easy to use web interfaces. Also, you can debug locally on your machine of choice. This also lets you leverage the same function code run on other targets like Azure Stack, IoT Edge, Cloud Service, and so on.

We hope you gathered enough information on Azure Functions. For more technical blogs, stay tuned with us!

How to stay motivated for studying the whole day?

At the derivation of the pandemic, I was very productive but soon after it turned into worry time. It is difficult for everyone to stay motivated the whole time all we do is search for ways to get out of it. I started exploring how to stay productive the whole day and found my ways to be productive and satisfied.

In this article, you will find the methods to stay the productive whole day, if depression gets on your nerves.

Exercise

You might have heard about it from everyone, doing exercise keeps your mind active and body strengthened. If you are too apathetic to do exercise don’t worry, go for a walk with the music on, and everything will fall in place. You will feel the energy to start work again and sit for the next three hours with better focus power. You can even go for meditation, to increase focus. It’s hard to start, but you have to do it for at least two weeks to make it a practice. Trick your mind always if it procrastinates the idea of doing exercise, meditation.

Work in Pauses

Sitting for 3-4 hours continuously might affect the focus, divide sitting hours into small parts like 1-2 hours, take a half an hour break and you are ready to work again with full concentration. It’s not necessary to take a break until you get distracts or lose focus or start scrolling social media. If you start overthinking or daydreaming it’s time to take a break. Watch funny videos, dance, sing, eat snacks, or drink something, this will energize you.

Switch tasks

If you get bored doing the same thing the whole day, do something that makes you happy. If you like swimming, gaming, dancing, singing, or code do it. It gives time to your brain to rejuvenates the cells that got damaged. You can take a small powerful nap, to recharge your whole body.

Read

Reading is one of the efficient ways of learning, if you want to give rest to your body, lay down on the bed and read articles, read books, or work on the phone. It’s good being lazy sometimes, to give time to yourself, and learn things anyhow.

Planning

Do not learn anything randomly. Have a plan, every successful person has a day planner. Before sleeping make a plan for the next day, so that you do not sit blank when you wake up and start thinking about where to start, it might ruin the starting of the day. If you don’t have a plan, you might not find a reason to wake up. It’s great to start the day with great energy, and a plan to process. This will turn your whole day productive and you will be able to complete all the tasks on the planner. This will make you feel lighter and special. 

I hope you get an insight into how to stay productive and energetic despite getting depressed and thinking about what to do the whole time.

Top 30 MongoDB Interview Questions And Answers

MongoDB requires skill and complex coding knowledge. Interviewers often ask tricky questions to test whether candidates are perfect for the job or not. So, while preparing for Interview questions, aspirants must have complete knowledge of this database. We have come up with the top 30 questions that mostly ask by interviewers. Have a look!

Q1. What do you understand by MongoDB?

MongoDB is a popular database for modern applications. This document-based database is highly scalable and quite good at performance.

Q2. Why MongoDB is counted amongst the best?

Since it’s the NoSQL database, comes with the following features-

High Performance

Document-oriented

Easy scalability

High availability

Rich query language

Q3. Define the role of profiler in MongoDB?

The profiler role is to show the performance & analyzing every operation characteristics. On using profilers, you will get all queries that are slower than usual. 

Q4. Compare MongoDB with CouchbaseDB and Couchbase?

Though MongoDB, CouchbaseDB, Couchbase are similar in several aspects, yet when it comes to crossing points, model execution, duplication, storage, etc, these are different. 

Q5. When to use namespace in MongoDb?

At the time of the sequencing database names & the collection, we make use of namespace. 

Q6. On removing object attribute. Would it be erased from the MongoDB as well?

Yes, it would be deleted. Thus, it’s better to eliminate an object attribute and save it again. 

Q7. Is there any way of moving the old file to the moveChunk?

Yes, you can do that. Once you are done with the functions, whatever old files you have changed to backup files & then you can move to these files into the directory of moveChunk during slices balancing. 

Q8. How this database provides you with consistency?

This database makes use of reader-writer locks. It means this allows users to access any supply such as database & collections simultaneously. Plus, it also provides private access straight to single writes. 

Q9. What is the full form of CRUD?

MongoDB gives you with CRUD operations and it stands for

C- Create

R- Read

U-Update

D- Delete

Q10. What do you understand by Sharding?

Storing data on multiple machines is called Sharding in MongoDB. This is done to accomplish the requirements of data growth. A horizontal partition is formed in the database & each partition is named as shard or database shard.

Q11. Which syntax in MongoDB you will use for creating a collection?

The following syntax will be used for creating a collection–

Q12. To drop collection, what syntax you will use?

This is the syntax we use to drop collection-

Q13. Replication – What is it?

Replication is a process that helps to synchronize data across several servers. Since database servers having multiple copies of data, replication prevents the database to lose the data from a single server. This also ensures that it would recover from service interruptions and hardware failure. 

Q14. GridFS is widely used in MongoDB. Why we use it?

GridFS basically used for retrieving and strong large files such as image, audio, video files.

Q15. Highlight the use of Journaling?

Well, Journaling is used for the MongoDB safe backups. 

Q16. What is the difference between MySQL and MongoDB? 

No doubt, both are open source databases and free of cost. But there are several things that separate one from another. They are different in terms of relationship, data representation, schema design & definition, normalization, performance speed, and much more. The biggest difference is – MySQL is a relational database whereas MongoDB is a non-relational database. 

Q17. MongoDB is written in which language?

MongoDB is written in C++. However, client and driver libraries are written in their own respective language. Though, some drivers make use of C extensions to enhance performance.

Q18. When you create a schema in MongoDB, what are the things that you need to consider?

There are following things that need to be considered while creating a schema in MongoDB – 

Design schema as per the requirements of users

Do joins when it’s on write, not when it’s on read

If you want to use objects together, combine them into 1 document. Otherwise, separate them

Optimize schema for most frequent use cases

Do complex aggregation in the schema

Q19. Write the syntax of the skip() method?

The syntax of the skip() method is –

Q20. Why we use the pretty() method?

This is used for showing results in a formatted way.

Q21 Why we use the NoSQL database?

As we know, today’s internet is loaded with big users & big data which are making the whole thing complex with each passing day. NoSQL is simply the answer to all your worries. It’s not a conventional database management system. It’s quite easy to handle just because it’s not inter-related with the other databases. Moreover, it efficiently handles all types of complicated, messy, and unstructured data. MongoDB is also a NoSQL database. 

Q22. What are the Sharded cluster components?

The sharded cluster components are- Shards, Config servers, and Query routers

Q23. Which command will you use for creating a database?

We use the Database_Name command for creating a database. 

Q24. Name that command is being used to check a connection?

We use the following command to check the connection

Q25. Define primary as well as secondary replica set?

All the write operations are accepted from clients in primary replica set whereas the secondary replica set’s oplog & applies operations to their datasets. It means primary replica sets are reflected by secondary datasets.

Q26 How you can update your documents in the collection?

Save () and update() are two methods via which we can achieve this. 

Q27. Define the Aggregation pipeline in one line. 

The aggregation pipeline is a framework that is used to perform aggregation tasks. The aggregation pipeline ultimately transforms documents into aggregated results. 

Q28. What do you understand by Horizontal and Vertical scaling?

Horizontal scaling distributes data over multiple shards or servers. It simply divides the dataset. However, vertical scaling adds more storage resources and CPU to enhance capacity. 

Q29. Which method you will use for creating an index?

createIndex() for creating an index in MongoDB.

Q30. Why do we use Dot notation?

For accessing elements of the array & embedded document field, MongoDB makes use of Dot notation. 

These are some of the most important questions that are often asked by the interviewer to test your knowledge and skills. So, the next time you are ready to go for an interview, make sure you have gone through all these questions. All the Best!
