#Postgresql documentation

[thewinastudyblog]

a day in my life as an web development intern (16/06)

i’m currently interning as a backend developer and am responsible for building an API using Flask(Python) and Postgresql.

09 - 10 = get there, turn on my laptop and open all the apps i need, most of the time it’s PyCharm for coding and Chrome cause I google a LOT. I also spend the first few 15 minutes trying to remember where I am and what I am supposed to do during the dat. and sometimes during this first hour I go get coffee.

10 - 11:30 = for my API, i needed to find a dataset that has all the schools in France with their gps coordinates, and so basically I found a database and wrote a python script to extract the data needed and then try to put a sample into my database.

11:30 - 12:30 = just like the schools, i also needed all the hospitals in france, and when I started looking at the dataset I was going to use for this I realized that there was no way I would get the gps coordinates from this specific dataset.

12:30 - 13:30 = here i went back home and ate a quick lunch.

13:30 - 15:30 = i found a better dataset and so i wrote a script to get the data i wanted from it and also tested putting some data into my database and made sure it worked. this script also involved clinics and nursing homes for the elderly cause I also needed them for my API. 15:30 - 17:00 = around this time I started trying to put all the data I imported from the school and hospital datasets into my database, and at one point I ran into some schools that didn't have a longitude and latitude, and I was like how do I fix that. So I spent around 30 mins googling and trying to write a script that could convert addresses into latitude and longitude, but it wasn't perfect LOL. 17:00 - 17:15 = spoke quickly to my supervisor abt this issue and what could be done about it 17:15 = turn off my laptop and monitors, pack my bag and go home.

as a whole, today was kinda fun ? even tho it was mostly spent struggling and trying to figure out how to do every single thing without using chatgpt (only used it once and it was at a time of dire need so I'm really proud of myself). honestly it's way more fun not using chatgpt cause you get to truly learn how to read documentation and know on your own how things work, and you also learn so much from trying and failing and i personally enjoy it so much !!! but yeah anyways, what's coming is definitely harder than what i've already done, but I've never been more ready. here's to more days of proving to myself over and over again how powerful my brain actually is and how good i am at this.

DBMS Tutorial for Beginners: Unlocking the Power of Data Management

In this "DBMS Tutorial for Beginners: Unlocking the Power of Data Management," we will explore the fundamental concepts of DBMS, its importance, and how you can get started with managing data effectively.

What is a DBMS?

A Database Management System (DBMS) is a software tool that facilitates the creation, manipulation, and administration of databases. It provides an interface for users to interact with the data stored in a database, allowing them to perform various operations such as querying, updating, and managing data. DBMS can be classified into several types, including:

Hierarchical DBMS: Organizes data in a tree-like structure, where each record has a single parent and can have multiple children.

Network DBMS: Similar to hierarchical DBMS but allows more complex relationships between records, enabling many-to-many relationships.

Relational DBMS (RDBMS): The most widely used type, which organizes data into tables (relations) that can be linked through common fields. Examples include MySQL, PostgreSQL, and Oracle.

Object-oriented DBMS: Stores data in the form of objects, similar to object-oriented programming concepts.

Why is DBMS Important?

Data Integrity: DBMS ensures the accuracy and consistency of data through constraints and validation rules. This helps maintain data integrity and prevents anomalies.

Data Security: With built-in security features, DBMS allows administrators to control access to data, ensuring that only authorized users can view or modify sensitive information.

Data Redundancy Control: DBMS minimizes data redundancy by storing data in a centralized location, reducing the chances of data duplication and inconsistency.

Efficient Data Management: DBMS provides tools for data manipulation, making it easier for users to retrieve, update, and manage data efficiently.

Backup and Recovery: Most DBMS solutions come with backup and recovery features, ensuring that data can be restored in case of loss or corruption.

Getting Started with DBMS

To begin your journey with DBMS, you’ll need to familiarize yourself with some essential concepts and tools. Here’s a step-by-step guide to help you get started:

Step 1: Understand Basic Database Concepts

Before diving into DBMS, it’s important to grasp some fundamental database concepts:

Database: A structured collection of data that is stored and accessed electronically.

Table: A collection of related data entries organized in rows and columns. Each table represents a specific entity (e.g., customers, orders).

Record: A single entry in a table, representing a specific instance of the entity.

Field: A specific attribute of a record, represented as a column in a table.

Step 2: Choose a DBMS

There are several DBMS options available, each with its own features and capabilities. For beginners, it’s advisable to start with a user-friendly relational database management system. Some popular choices include:

MySQL: An open-source RDBMS that is widely used for web applications.

PostgreSQL: A powerful open-source RDBMS known for its advanced features and compliance with SQL standards.

SQLite: A lightweight, serverless database that is easy to set up and ideal for small applications.

Step 3: Install the DBMS

Once you’ve chosen a DBMS, follow the installation instructions provided on the official website. Most DBMS solutions offer detailed documentation to guide you through the installation process.

Step 4: Create Your First Database

After installing the DBMS, you can create your first database. Here’s a simple example using MySQL:

Open the MySQL command line or a graphical interface like MySQL Workbench. Run the following command to create a new CREATE DATABASE my_first_database;

Use the database: USE my_first_database;

Step 5: Create Tables

Next, you’ll want to create tables to store your data. Here’s an example of creating a table for storing customer information:

CREATE TABLE customers ( 2 customer_id INT AUTO_INCREMENT PRIMARY KEY, 3 first_name VARCHAR(50), 4 last_name VARCHAR(50), 5 email VARCHAR(100), 6 created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP 7);

In this example, we define a table named customers with fields for customer ID, first name, last name, email, and the date the record was created.

Step 6: Insert Data

Now that you have a table, you can insert data into it. Here’s how to add a new customer:

1 INSERT INTO customers (first_name, last_name, email) 2VALUES ('John', 'Doe', 'john.doe@example.com');

Query Data

To retrieve data from your table, you can use the SELECT statement. For example, to get all customers:

1 SELECT * FROM customers;

You can also filter results using the WHERE clause:

SELECT * FROM customers WHERE last_name = 'Doe';

Step 8: Update and Delete Data

You can update existing records using the UPDATE statement:

UPDATE customers SET email = 'john.new@example.com' WHERE customer_id = 1;

To delete a record, use the DELETE statement:

DELETE FROM customers WHERE customer_id = 1;

Conclusion

In this "DBMS Tutorial for Beginners: Unlocking the Power of Data Management," we’ve explored the essential concepts of Database Management Systems and how to get started with managing data effectively. By understanding the importance of DBMS, familiarizing yourself with basic database concepts, and learning how to create, manipulate, and query databases, you are well on your way to becoming proficient in data management.

As you continue your journey, consider exploring more advanced topics such as database normalization, indexing, and transaction management. The world of data management is vast and full of opportunities, and mastering DBMS will undoubtedly enhance your skills as a developer or data professional.

With practice and experimentation, you’ll unlock the full potential of DBMS and transform the way you work with data. Happy database management!
