Prospective Study: Sea Cucumber Flour as a Food Supplement

Sea cucumbers (holoturia) are considered a dietary delicacy, being widely used in medicinal healing by Asians over the centuries; they are rich in bioactive compounds with the potential to exert several actions in the body, namely: Anticancer, anticoagulant, antihypertensive, anti-inflammatory, antimicrobial, antioxidant, antithrombotic and antitumor. The sea cucumber drying process, as used for the flour production, maintains their functional properties. Thus, in view of the benefits associated with the consumption of sea cucumber to human health, evidenced by scientific research, a market diagnosis was carried out for its flour as a food supplement. This study aimed to carry out market research to assess the interest of Brazilians in the consumption of sea cucumber flour. Market prospecting research for sea cucumber flour was carried out using the survey monkey tool. The structured questionnaire consisted of ten closed questions, which were answered by 100 people. The public interviewed was heterogeneous: 36% between 15 and 25 years old; 11% between 26 and 35 years old; 12% between 36 and 45 years old, 18% between 46 and 55 years old and 23% of the public over 55 years old. About 97% claimed to have never consumed sea cucumbers or derivatives, but 91% expressed interest in consuming sea cucumber-based flour, given its nutraceutical potential. Among the levels of interest: 33% reasonable, 46% interested and 13% very interested; and 67% indicated the preferential acquisition in capsule form. Regarding the cost for 100g of the product: 64% would pay up to 3.89 dollars, 33% between 4.08 and 5.83 dollars and only 3% would pay more than 5.83 dollars. As for the frequency of consumption: 53% would consume daily. Conclusion: The research indicated market potential for sea cucumber flour, especially in capsules, as a food supplement. However, most of these animals come from extractive fisheries. Thus, it is a challenging task to reconcile the conservation need with the socioeconomic importance of fisheries. In this sense, to encourage the production of these organisms through aquaculture and the sea cucumber flour production with added value, will meet the prospects of the current market that seeks greaterhealthiness through nutrition and/or supplementation and foods with a lower carbon emission.

Answer of that question is high heat value What is the reason? Please explain because the same question I have seen 1st or second page.

If we take high heat value of oil in heat engine than fuel is evaporate because the fuels are volatile in nature and we not get full efficiency of fuel.That's why we So LHV of fuel is used in case of IC engine. Gases to the point where water vapor can be condensed and any latent heat is also utilized in the transfer process. In case of IC engine, where gasoline and diesel is used, it is possible to bring down the temperature of combustion Not possible to fully bring down the outlet temperature of gases to the point where water vapor is condensed.So, HHV is used. Similarly, in case of gas turbine, it is Rejected to the atmosphere, considering it is higher than the dew point of sulpher and preventing any sulpher droplet to form. At this temperature, still the combustion gases is having heat energy and can be used but it is The reason is theĬombustion products leave the stack at a temperature of about 130 C. For eg, in coal based thermal power plant, the HHV of coal is used. In whichĪpplication, the temperature can be brought back to the atmospheric condition. Now the real point is ,the decision, whether to use HHV or LHV depends solely on the type of application. So ,water vapor is not condensed in this case. Products reaches approximately, the ambient temperature.ĭefinition is, where the combustion products are not brought back to the atmospheric temperature. It means ,if we are using HHV of fuel, the heat energy is transferred until the temperature of the combustion So moreĪmount of heat is transferred if we consider HHV of fuel. Here, any water vapor which is present is condensed back by giving off its latent heat. Returned back to the initial state (atmospheric temperature, T = 25 C).

Name the languages used by Oracle Tuxedo? The software is written in 7 languages C C++ JAVA PYTHON COBOL Ruby PHP 5. What according to you is the greatest advantage of Tuxedo? The amazing clustering capability of Tuxedo is its greatest advantage. It can process millions of requests in a second. Being highly optimized it gets responses within few microseconds. 6. Which cluster is used by oracle? Oracle uses Oracle RAC or Real Application Cluster. 7. What is RAC? Oracle RAC is Oracle’s premier shared disk database clustering technology. It is a clustered database solution for scalability, high availability, flexibility and elasticity. RAC was introduced in 2001 with Oracle 9i. It is available in standard as well as enterprise edition. 8. What is difference between RAC & non RAC environment in Oracle? In case of Non RAC environment a single instance accesses a single database. The database contains control files, redo log files & database files which is physically present on desk. Whereas, The RAC environment contains two or more instances communicating with a single database ; these all are instances running on separate servers. 9. What is Oracle Exadata? Exadata is simply a data appliance. A data appliance is a server with pre-installed & pre-optimized database. Three major components of Exadata database server are DB Server , Cell Storage , Infiniband Switch , Cisco Switch , PDU , Database Instance , ASM Instance , Database Resource Manager The key Features of Oracle Exadata are Hardware level , Storage Server Cells , High Speed Infiniband Switch , Software level , Smart Scan , Flash Cache , Hybrid Columnar Compression , IORM (I/O Resource Manager). 10. How can we shift a normal database to Exadata? There are almost 9 possible ways to do that. Physical Standby Logical Standby Export/Import Transportable Tablespace Transportable Database Golden gate RMAN cold Oracle Streams Hot backup restoration

Oracle Tuxedo Interview Questions 11. What is ASM? ASM is Automatic storage management which was introduces in Oracle 10g . It provides storage solutions. It is a very powerful tool for managing multi-terabyte database. The storage components of Oracle ASM are ASM Disks ASM Disk groups ASM Allocation units ASM Extents ASM Files ASM File Extent Map ASM can add a disk from the volume or remove it, ASM can perform the load balancing inside the storage. Basically , ASM provides the volume manager layer which is essential for every software. It also acts as a file system. 12. What are the benefits of ASM? There are several benefits of ASM . The most important aspects of ASM are It stripes files rather than logical volumes It can perform Online disk reconfiguration and dynamic rebalancing It has adjustable rebalancing speed It Provides redundancy on a file basis Besides, ASM is Custer-aware and it can be automatically installed . 13. What are the temporal data types provided by Oracle? Oracle provides 3 kinds of data types- Date data type which provides different formats of dates. Timestamp data type which provides different formats of Time stamp. Interval data type which provides interval between dates & times. 14. What is SALT? SALT stands for service architecture leveraging tuxedo. It is a SOAP over https gateway. It was created to expose tuxedo services as web services which will invoke web services from within tuxedo applications using tuxedo API. SALT is configuration driven. It is scalable and highly available. Code changing is not required in case of SALT. 15. What is an Oracle instance? Oracle instance is a system global area (SGA) and the Oracle background processes constitute an Oracle database instance. Every time a database is started, a system global area is allocated and Oracle background processes are started. The SGA is deallocated when the instance shuts down. After starting an instance, Oracle associates the instance with the specified database. This is called mounting the database. The database is then ready to be opened, which makes it accessible to authorized users. 16. What is Oracle package? Oracle package is a schema object that groups logically related PL/SQL types, items, and subprograms. Packages offer several advantages: modularity, easier application design, information hiding, added functionality, and better performance 17. Explain the general concepts of PL/SQL? PL/SQL is Oracle's procedural extension to SQL. With PL/SQL, we can manipulate data with SQL statements, and control program flow with procedural constructs such as IF-THEN and LOOP. we can also declare constants and variables, define procedures and functions, use collections and object types, and trap run-time errors. Applications written using any of the Oracle programmatic interfaces can call PL/SQL stored procedures and send blocks of PL/SQL code to the server for execution. Because it runs inside the database, PL/SQL code is very efficient for data-intensive operations, and minimizes network traffic in client/server applications. 18. What is a database trigger? A database trigger is a stored procedure that Oracle invokes automatically when certain events occur, for example, when a DML operation modifies a certain table. Triggers enforce business rules, prevent incorrect values from being stored, and reduce the need to perform checking and cleanup operations in each application. Here are some important items to remember about triggers. -On insert triggers have no : OLD values. -On delete triggers have no :NEW values -Triggers do not commit transactions. If a transaction is rolled back, the data changed by the trigger is also rolled back. -Commits, rollbacks and save points are not allowed in the trigger body. A commit/rollback affects the entire transaction, it is all or none. -Unhandled exceptions in the trigger will cause a rollback of the entire transaction, not just the trigger. -If more than one trigger is defined on an event, the order in which they fire is not defined. If the triggers must fire in order, we must create one trigger that executes all the actions in the required order. -A trigger can cause other events to execute triggers. -A trigger cannot change a table that it has read from. 19. What is a data warehouse? A data warehouse is a relational database that is designed for query and analysis. It usually contains historical data derived from transaction data, but it can include data from other sources. It separates analysis workload from transaction workload and enables an organization to consolidate data from several sources. In addition to a relational database, a data warehouse environment includes an extraction, transportation, transformation, and loading (ETL) solution, an online analytical processing (OLAP) engine, client analysis tools, and other applications that manage the process of gathering data and delivering it to business users. Most data warehouses use a staging area to clean and process our operational data before We may want to customize our warehouse's architecture for different groups within our organization. 20. What is RDF? A set of rules (a sort of language) for creating descriptions of information, especially information available on the World Wide Web. RDF could be used to describe a collection of books, or artists, or a collection of web pages as in the RSS data format which uses RDF to create machine-readable summaries of web sites. RDF is also used in XPFE applications to define the relationships between different collections of elements, for example RDF could be used to define the relationship between the data in a database and the way that data is displayed to a user 21. What do the Oracle logical structures comprised of? Logical structures of an Oracle database include tablespaces, schema objects, data blocks, extents, and segments. Because the physical and logical structures are separate, the physical storage of data can be managed without affecting the access to logical storage structures. 22. Define cursor variable? A cursor variable is associated with different statements which can hold different values at run time. It is kind of reference type. 23. Describe PLS_INTEGER datatype? PLS_INTEGER and BINARY_INTEGER are identical datatypes and are only available in PL/SQL. You cannot create a column in a table with either of these data types. PLS_INTEGER is a highly efficient integer 32-bit data type. You will most commonly see PLS_INETGER (and BINARY_INETGER) in PL/SQL routines as an index variable. An associative array (INDEX BY TABLE) index. Both PLS_INTEGER and BINARY_INTEGER allow whole numbers only. Decimal fractions are rounded to the nearest whole number. 24. What is a pragma? Pragma is a keyword in Oracle PL/SQL that is used to provide an instruction to the compiler like PRAGMA AUTONOMOUS_TRANSACTION. 25. What is Oracle package? A schema object that groups logically related PL/SQL types, items, and subprograms. Packages offer several advantages: modularity, easier application design, information hiding, added functionality, and better performance. 26. What is partitioning? Partitioning is a method of splitting large tables and indexes into smaller, more manageable pieces. 27. What is the DCL & DDL language ? DCL is Data Control Language statements (GRANT, COMMIT) DDL (Data D DDL language definition Language) statements are used to define the database structure or schema (CREATE, ALTER, TRUNCATE). 28. What is EXPLANE PLAN? The EXPLAIN PLAN statement displays execution plans chosen by the Oracle optimizer for SELECT, UPDATE, INSERT, and DELETE statements. A statement's execution plan is the sequence of operations Oracle performs to run the statement. The row source tree is the core of the execution plan. It shows the following information: -An ordering of the tables referenced by the statement -An access method for each table mentioned in the statement -A join method for tables affected by join operations in the statement -Data operations like filter, sort, or aggregation In addition to the row source tree, the plan table contains information about the following: -Optimization, such as the cost and cardinality of each operation -Partitioning, such as the set of accessed partitions -Parallel execution, such as the distribution method of join inputs The EXPLAIN PLAN results let us determine whether the optimizer selects a particular execution plan, such as, nested loops join. 29. What is ERP System? Enterprise Resource Planning, a system that is used to manage all aspects of a company's operations. ERP is a way to integrate the data and processes of an organization into one single system. 30. What does TUXEDO mean? Transactions for UniX, Enhanced for Distributed Operation 31. Which companies owned TUXEDO before BEA? AT&T, USL, Novell. 32. What's the TUXEDO 'buddy' mechanism? The DBBL keeps the BBL up, the BBL keeps the DBBL (and all other servers) up.

Morning Update 9/25/19 Move The Pipeline - Save the Water Hats off to the Central Texas media that continue asking important questions about the mega-pipeline that Kinder Morgan wants to route through the Hill Country's karst aquifers, watersheds, rivers and park systems. Clearly, and in spite of Kinder Morgan's spin on the truth, the community outreach and stakeholder work that KM has done on the behemoth PHP is lacking. https://ift.tt/2n8T74O Case in point: See this local Fox News interview with the Kyle mayor. Reporter: "We asked Kinder Morgan on our show if it would release the environmental analysis on the pipeline's construction. They didn't give us a yes or a no." Mayor Mitchell: "That goes to illustrate the challenges that cities like Kyle are facing. Our residents are very concerned about environmental impact, safety impact . . . and at this point we don't really have any answers from Kinder Morgan." Evasive. Untruthful. Unaccountable. That's Kinder Morgan. Texans deserve better. #MoveThePipelineSaveTheWater Fox 7 to Kyle Mayor Travis Mitchell: "Have you seen the environmental report?" Mitchell: "No, no we haven't." —————————— A lot of you have asked us to include Kinder Morgan's contact info on every email Rich Kinder - Chairman - richardkinder@kindermorgan.com Anthony Ashley - Investor Relations - anthony_ashley@kindermorgan.com Allen Fore - Public Affairs - allen_fore@kindermorgan.com

Top 25 Python Interview Questions and Answers asked in Interview

Here the top 25 Python interview questions and answers to help you crack your Python Interview. If you want to learn Practical Python Training then please goes through this Python Classes in Pune.

Q1. What is the difference between list and tuples in Python?

LIST vs TUPLESLISTTUPLESLists are mutable i.e they can be edited.Tuples are immutable (tuples are lists which can’t be edited).Lists are slower than tuples.Tuples are faster than list.Syntax: list_1 = [10, ‘Chelsea’, 20]Syntax: tup_1 = (10, ‘Chelsea’ , 20)

Q2. What are the key features of Python?

Python is an interpreted language. That means that, unlike languages like C and its variants, Python does not need to be compiled before it is run. Other interpreted languages include PHP and Ruby.

Python is dynamically typed, this means that you don’t need to state the types of variables when you declare them or anything like that. You can do things like x=111 and then x=”I’m a string” without error

Python is well suited to object orientated programming in that it allows the definition of classes along with composition and inheritance. Python does not have access specifiers (like C++’s public, private).

In Python, functions are first-class objects. This means that they can be assigned to variables, returned from other functions and passed into functions. Classes are also first class objects

Writing Python code is quick but running it is often slower than compiled languages. Fortunately，Python allows the inclusion of C based extensions so bottlenecks can be optimized away and often are. The numpy package is a good example of this, it’s really quite quick because a lot of the number crunching it does isn’t actually done by Python

Python finds use in many spheres — web applications, automation, scientific modeling, big data applications and many more. It’s also often used as “glue” code to get other languages and components to play nice.

Q3. What type of language is python? Programming or scripting?

Ans: Python is capable of scripting, but in general sense, it is considered as a general-purpose programming language. To know more about Scripting, you can refer to the Python Scripting Tutorial.

Q4.How is Python an interpreted language?

Ans: An interpreted language is any programming language which is not in machine level code before runtime. Therefore, Python is an interpreted language.

Q5.What is pep 8?

Ans: PEP stands for Python Enhancement Proposal. It is a set of rules that specify how to format Python code for maximum readability.

Q6. How is memory managed in Python?

Ans:

Memory management in python is managed by Python private heap space. All Python objects and data structures are located in a private heap. The programmer does not have access to this private heap. The python interpreter takes care of this instead.

The allocation of heap space for Python objects is done by Python’s memory manager. The core API gives access to some tools for the programmer to code.

Python also has an inbuilt garbage collector, which recycles all the unused memory and so that it can be made available to the heap space.

Q7. What is namespace in Python?

Ans: A namespace is a naming system used to make sure that names are unique to avoid naming conflicts.

Q8. What is PYTHONPATH?

Ans: It is an environment variable which is used when a module is imported. Whenever a module is imported, PYTHONPATH is also looked up to check for the presence of the imported modules in various directories. The interpreter uses it to determine which module to load.

Q9. What are python modules? Name some commonly used built-in modules in Python?

Ans: Python modules are files containing Python code. This code can either be functions classes or variables. A Python module is a .py file containing executable code.

Some of the commonly used built-in modules are:

os

sys

math

random

data time

JSON

Q10.What are local variables and global variables in Python?

Global Variables:

Variables declared outside a function or in global space are called global variables. These variables can be accessed by any function in the program.

Local Variables:

Any variable declared inside a function is known as a local variable. This variable is present in the local space and not in the global space.

Example:

a=2

defadd():

b=3

c=a+b

print(c)

add()

Output: 5

When you try to access the local variable outside the function add(), it will throw an error.

Q11. Is python case sensitive?

Ans: Yes. Python is a case sensitive language.

Q12.What is type conversion in Python?

Ans: Type conversion refers to the conversion of one data type iinto another.

int() — converts any data type into integer type

float() — converts any data type into float type

ord() — converts characters into integer

hex() — converts integers to hexadecimal

oct() — converts integer to octal

tuple() — This function is used to convert to a tuple.

set() — This function returns the type after converting to set.

list() — This function is used to convert any data type to a list type.

dict() — This function is used to convert a tuple of order (key,value) into a dictionary.

str() — Used to convert integer into a string.

complex(real,imag) — This functionconverts real numbers to complex(real,imag) number.

Q13. How to install Python on Windows and set path variable?

Ans: To install Python on Windows, follow the below steps:

Install python from this link: https://www.python.org/downloads/

After this, install it on your PC. Look for the location where PYTHON has been installed on your PC using the following command on your command prompt: cmd python.

Then go to advanced system settings and add a new variable and name it as PYTHON_NAME and paste the copied path.

Look for the path variable, select its value and select ‘edit’.

Add a semicolon towards the end of the value if it’s not present and then type %PYTHON_HOME%

Q14. Is indentation required in python?

Ans: Indentation is necessary for Python. It specifies a block of code. All code within loops, classes, functions, etc is specified within an indented block. It is usually done using four space characters. If your code is not indented necessarily, it will not execute accurately and will throw errors as well.

Q15. What is the difference between Python Arrays and lists?

Ans: Arrays and lists, in Python, have the same way of storing data. But, arrays can hold only a single data type element whereas lists can hold any data type elements.

Example:

importarray as arr

My_Array=arr.array(‘i’,[1,2,3,4])

My_list=[1,’abc’,1.20]

print(My_Array)

print(My_list)

Output:

array(‘i’, [1, 2, 3, 4]) [1, ‘abc’, 1.2]

Q16. What are functions in Python?

Ans: A function is a block of code which is executed only when it is called. To define a Python function, the def keyword is used.

Example:

defNewfunc():

print(“Hi, Welcome to Cyber Success”)

Newfunc(); #calling the function

Output: Hi, Welcome to Cyber Success

Q17.What is __init__?

Ans: __init__ is a method or constructor in Python. This method is automatically called to allocate memory when a new object/ instance of a class is created. All classes have the __init__ method.

Here is an example of how to use it.

classEmployee:

def__init__(self, name, age,salary):

self.name =name

self.age =age

self.salary =20000

E1 =Employee(“XYZ”, 23, 20000)

# E1 is the instance of class Employee.

#__init__ allocates memory for E1.

print(E1.name)

print(E1.age)

print(E1.salary)

Output:

XYZ

23

20000

Q18.What is a lambda function?

Ans: An anonymous function is known as a lambda function. This function can have any number of parameters but, can have just one statement.

Example:

a =lambdax,y : x+y

2. print(a(5, 6))

Output: 11

Q 19 What is self in Python?

Ans: Self is an instance or an object of a class. In Python, this is explicitly included as the first parameter. However, this is not the case in Java where it’s optional. It helps to differentiate between the methods and attributes of a class with local variables.

The self variable in the init method refers to the newly created object while in other methods, it refers to the object whose method was called.

Q20. How does break, continue and pass work?

BreakAllows loop termination when some condition is met and the control is transferred to the next statement.ContinueAllows skipping some part of a loop when some specific condition is met and the control is transferred to the beginning of the loopPassUsed when you need some block of code syntactically, but you want to skip its execution. This is basically a null operation. Nothing happens when this is executed.

Q21. What does [::-1} do?

Ans: [::-1] is used to reverse the order of an array or a sequence.

For example:

importarray as arr

2. My_Array=arr.array(‘i’,[1,2,3,4,5])

3. My_Array[::-1]

Output: array(‘i’, [5, 4, 3, 2, 1])

[::-1] reprints a reversed copy of ordered data structures such as an array or a list. the original array or list remains unchanged.

Q22. How can you randomize the items of a list in place in Python?

Ans: Consider the example shown below:

fromrandom importshuffle

x =[‘Keep’, ‘The’, ‘Blue’, ‘Flag’, ‘Flying’, ‘High’]

shuffle(x)

print(x)

The output of the following code is as below.

[‘Flying’, ‘Keep’, ‘Blue’, ‘High’, ‘The’, ‘Flag’]

Q23. What are python iterators?

Ans: Iterators are objects which can be traversed though or iterated upon.

Q24. How can you generate random numbers in Python?

Ans: Random module is the standard module that is used to generate a random number. The method is defined as:

importrandom

2. random. Random

The statement random. Random () method return the floating point number that is in the range of [0, 1). The function generates random float numbers. The methods that are used with the random class are the bound methods of the hidden instances. The instances of the Random can be done to show the multi-threading programs that creates a different instance of individual threads. The other random generators that are used in this are:

randrange (a, b): it chooses an integer and define the range in-between [a, b). It returns the elements by selecting it randomly from the range that is specified. It doesn’t build a range object.

uniform (a, b): it chooses a floating point number that is defined in the range of [a, b). Iyt returns the floating point number

normalvariate (mean, sdev): it is used for the normal distribution where the mu is a mean and the sdev is a sigma that is used for standard deviation.

The Random class that is used and instantiated creates an independent multiple random number generator.

Q25. What is the difference between range & xrange?

Ans: For the most part, xrange and range are the exact same in terms of functionality. They both provide a way to generate a list of integers for you to use, however you please. The only difference is that range returns a Python list object and x range returns an xrange object.

This means that xrange doesn’t actually generate a static list at run-time like range does. It creates the values as you need them with a special technique called yielding. This technique is used with a type of object known as generators. That means that if you have a really gigantic range you’d like to generate a list for, say one billion, xrange is the function to use.

This is especially true if you have a really memory sensitive system such as a cell phone that you are working with, as range will use as much memory as it can to create your array of integers, which can result in a Memory Error and crash your program. It’s a memory hungry beast.

There are 3 approaches to earn variety in JavaScript. For instance, if you're comparing two strings, then they need to have character sets. A Python documentation string is known as docstring, it's a manner of documenting functions, modules and courses. All objects but the majority of those can't be copied by you. Objects aren't the only means. Objects and behaviors are tacked on the same thing, which may be obtained randomly by numerous functions with order, which might lead to undesirable behaviour like race conditions. The type attribute can be utilized to modify the numbering type. Along with basic knowledge and abilities, you wish to consider attributes like overall expert experience and the capability to function within a team. Two factors containing objects that are identical are not equal to each other because they do point at the exact same object. The function takes an integer that specifies the chain must be replicated. http://bit.ly/2kA8ySD It would be simple to wrap our function to determine whether it is well worth making a purchase. The evaluation comprises 25 questions and there is no time limitation. For that reason, it is considered best practice to have variables declared at the cover of the area they'll be utilized to safeguard against hoisting. The second principle ends in the recursive function. A case of Stack might be a heap of books placed in a purchase.

MonggoDB provides official driver support for C, C++, C#, Java, Node.js, Perl, PHP, Python, Ruby, Scala, Go and Erlang. You can use MongoDB with any of the above languages. There are some other community supported drivers too but the above mentioned ones are officially provided by MongoDB. 3. What are the different types of NoSQL databases? Give some example. NoSQL database can be classified as 4 basic types: Key value store NoSQL database Document store NoSQL database Column store NoSQL database Graph base NoSQL databse There are many NoSQL databases. MongoDB, Cassandra, CouchBD, Hypertable, Redis, Riak, Neo4j, HBASE, Couchbase, MemcacheDB, Voldemort, RevenDB etc. are the examples of NoSQL databases. 4. Is MongoDB better than other SQL databases? If yes then how? MongoDB is better than other SQL databases because it allows a highly flexible and scalable document structure. For example: One data document in MongoDB can have five columns and the other one in the same collection can have ten columns. MongoDB database are faster than SQL databases due to efficient indexing and storage techniques. 5. What type of DBMS is MongoDB? MongoDB is a document oriented DBMS 6. What is the difference between MongoDB and MySQL? Although MongoDB and MySQL both are free and open source databases, there is a lot of difference between them in the term of data representation, relationship, transaction, querying data, schema design and definition, performance speed, normalization and many more. To compare MySQL with MongoDB is like a comparison between Relational and Non-relational databases. 7. Why MongoDB is known as best NoSQL database? MongoDb is the best NoSQL database because, it is: Document Oriented Rich Query language High Performance Highly Available Easily Scalable 8. Does MongoDB support primary-key, foreign-key relationship? No. By Default, MongoDB doesn't support primary key-foreign key relationship. 9. Can you achieve primary key - foreign key relationships in MongoDB? We can achieve primary key-foreign key relationship by embedding one document inside another. For example: An address document can be embedded inside customer document. 10. Does MongoDB need a lot of RAM? No. There is no need a lot of RAM to run MongoDB. It can be run even on a small amount of RAM because it dynamically allocates and de-allocates RAM according to the requirement of the processes.

MongoDB Interview Questions 11. Explain the structure of ObjectID in MongoDB. ObjectID is a 12-byte BSON type. These are: 4 bytes value representing seconds 3 byte machine identifier 2 byte process id 3 byte counter 12. Is it true that MongoDB uses BSON to represent document structure? Yes. 13. What are Indexes in MongoDB? In MondoDB, Indexes are used to execute query efficiently. Without indexes, MongoDB must perform a collection scan, i.e. scan every document in a collection, to select those documents that match the query statement. If an appropriate index exists for a query, MongoDB can use the index to limit the number of documents it must inspect. 14. By default, which index is created by MongoDB for every collection? By default, the_id collection is created for every collection by MongoDB. 15. What is a Namespace in MongoDB? Namespace is a concatenation of the database name and the collection name. Collection, in which MongoDB stores BSON objects. 16. Can journaling features be used to perform safe hot backups? Yes. 17. Why does Profiler use in MongoDB? MongoDB uses a database profiler to perform characteristics of each operation against the database. You can use a profiler to find queries and write operations 18. If you remove an object attribute, is it deleted from the database? Yes, it be. Remove the attribute and then re-save(. the object. 19. In which language MongoDB is written? MongoDB is written and implemented in C++. 20. Does MongoDB need a lot space of Random Access Memory (RAM)? No. MongoDB can be run on small free space of RAM. 21. What language you can use with MongoDB? MongoDB client drivers supports all the popular programming languages so there is no issue of language, you can use any language that you want. 22. Does MongoDB database have tables for storing records? No. Instead of tables, MongoDB uses "Collections" to store data. 23. Do the MongoDB databases have schema? Yes. MongoDB databases have dynamic schema. There is no need to define the structure to create collections. 24. What is the method to configure the cache size in MongoDB? MongoDB's cache is not configurable. Actually MongoDb uses all the free spaces on the system automatically by way of memory mapped files. 25. How to do Transaction/locking in MongoDB? MongoDB doesn't use traditional locking or complex transaction with Rollback. MongoDB is designed to be light weighted, fast and predictable to its performance. It keeps transaction support simple to enhance performance. 26. Why 32 bit version of MongoDB are not preferred ? Because MongoDB uses memory mapped files so when you run a 32-bit build of MongoDB, the total storage size of server is 2 GB. But when you run a 64-bit build of MongoDB, this provides virtually unlimited storage size. So 64-bit is preferred over 32-bit. 27. Is it possible to remove old files in the moveChunk directory? Yes, These files can be deleted once the operations are done because these files are made as backups during normal shard balancing operation. This is a manual cleanup process and necessary to free up space. 28. What will have to do if a shard is down or slow and you do a query? If a shard is down and you even do query then your query will be returned with an error unless you set a partial query option. But if a shard is slow them Mongos will wait for them till response. 29. Explain the covered query in MongoDB. A query is called covered query if satisfies the following two conditions: The fields used in the query are part of an index used in the query. The fields returned in the results are in the same index. 30. What is the importance of covered query? Covered query makes the execution of the query faster because indexes are stored in RAM or sequentially located on disk. It makes the execution of the query faster. Covered query makes the fields are covered in the index itself, MongoDB can match the query condition as well as return the result fields using the same index without looking inside the documents. 31. What is sharding in MongoDB? In MongoDB, Sharding is a procedure of storing data records across multiple machines. It is a MongoDB approach to meet the demands of data growth. It creates horizontal partition of data in a database or search engine. Each partition is referred as shard or database shard. 32. What is replica set in MongoDB? A replica can be specified as a group of mongo instances that host the same data set. In a replica set, one node is primary, and another is secondary. All data is replicated from primary to secondary nodes. 33. What is primary and secondary replica set in MongoDB? In MongoDB, primary nodes are the node that can accept write. These are also known as master nodes. The replication in MongoDB is single master so, only one node can accept write operations at a time. Secondary nodes are known as slave nodes. These are read only nodes that replicate from the primary. 34. By default, which replica sets are used to write data? By default, MongoDB writes data only to the primary replica set. 35. What is CRUD in MongoDB? MongoDB supports following CRUD operations: Create Read Update Delete 36. In which format MongoDB represents document structure? MongoDB uses BSON to represent document structures. 37. What will happen when you remove a document from database in MongoDB? Does MongoDB remove it from disk? Yes. If you remove a document from database, MongoDB will remove it from disk too. 38. Why are MongoDB data files large in size? MongoDB doesn't follow file system fragmentation and pre allocates data files to reserve space while setting up the server. That's why MongoDB data files are large in size. 39. What is a storage engine in MongoDB? A storage engine is the part of a database that is used to manage how data is stored on disk. For example: one storage engine might offer better performance for read-heavy workloads, and another might support a higher-throughput for write operations. 40. Which are the storage engines used by MongoDB? MMAPv1 and WiredTiger are two storage engine used by MongoDB. 41. What is the usage of profiler in MongoDB? A database profiler is used to collect data about MongoDB write operations, cursors, database commands on a running mongod instance. You can enable profiling on a per-database or per-instance basis. The database profiler writes all the data it collects to the system. profile collection, which is a capped collection. 42. Is it possible to configure the cache size for MMAPv1 in MongoDB? No. it is not possible to configure the cache size for MMAPv1 because MMAPv1 does not allow configuring the cache size. 43. How to configure the cache size for WiredTiger in MongoDB? For the WiredTiger storage engine, you can specify the maximum size of the cache that WiredTiger will use for all data. This can be done using storage.wiredTiger.engineConfig.cacheSizeGB option. 44. How does MongoDB provide concurrency? MongoDB uses reader-writer locks for concurrency. Reader-writer locks allow concurrent readers shared access to a resource, such as a database or collection, but give exclusive access to a single write operation. 45. What is the difference between MongoDB and Redis database? Difference between MongoDB and Redis: Redis is faster than MongoDB. Redis has a key-value storage whereas MongoDB has a document type storage. Redis is hard to code but MongoDB is easy. 46. What is the difference between MongoDB and CouchDB? Difference between MongoDB and CouchDB: MongoDB is faster than CouchDB while CouchDB is safer than MongoDB. Triggers are not available in MongoDB while triggers are available in CouchDB. MongoDB serializes JSON data to BSON while CouchDB doesn't store data in JSON format. 47. What is the difference between MongoDB and Cassandra? Difference between MongoDB and Cassandra: MongoDB is cross-platform document-oriented database system while Cassandra is high performance distributed database system. MongoDB is written in C++ while Cassandra is written in Java. MongoDB is easy to administer in the case of failure while Cassandra provides high availability with no single point of failure. 48. Is there any need to create database command in MongoDB? You don't need to create a database manually in MongoDB because it creates automaically when you save the value into the defined collection at first time. 49. What do you understand by NoSQL databases? Is MongoDB a NoSQL database? explain. At the present time, the internet is loaded with big data, big users, big complexity etc. and also becoming more complex day by day. NoSQL is answer of all these problems, It is not a traditional database management system, not even a relational database management system (RDBMS). NoSQL stands for "Not Only SQL". NoSQL is a type of database that can handle and sort all type of unstructured, messy and complicated data. It is just a new way to think about the database. Yes. MongoDB is a NoSQL database.

I’m sure you’ve heard of this one before and if you’re not sure what it is; let me translate it to a more recognizable name: Networking. For the ones who are aware of what it is I’m sure you’ve had your own experiences that you’ll never forget, and experiences to share.

Embed from Getty Imageswindow.gie=window.gie||function(c){(gie.q=gie.q||[]).push(c)};gie(function(){gie.widgets.load({id:'5n_5oOgITUFSewPpbwgI1A',sig:'uEGJoyC1JQMGt_iw-exu7rQdVjYFJTB1DSKcsHCUVsM=',w:'414px',h:'414px',items:'165930354',caption: false ,tld:'com',is360: false })});

Here in the Philippines this is a fairly common “business” and it’s not just limited to the purveying of cosmetic wares, but also jobs such as data encoding, E-loading, captcha typing and more (I’m looking at you Plan Pro Matrix). But the common one here is the scheme that involves cosmetics and these are the kind that would sell you glutathione soaps such as Luxxe white (Looking at you too Frontrow).

One arsehole actually wasted my time back then and I’ll get to that in a bit. I gotta hand it to these folks; they really think of everything just to make a quick buck.

If you’re not the type of person that likes reading long articles; here’s my takeaway:

If someone invites you to a “seminar” and it smells like it’s an offer that says you’ll make money and is really intent on getting you on the hype train. It’s a damn scam. And if they shell out products for you to resell. That’s the red flag.

Moreover you’ll see these commonly on facebook and some other blogs owned by these folks:

This slideshow requires JavaScript.

Why the hell should you drop so much money just to be a member? Trying to sell you glutathione products that way or recruit you into selling them? That’s the laziest method of trying to sell something.

If you’re gonna buy a whitening soap, don’t buy from these poor fellows; they should wake up and realize that they’re just wasting time there.

I know there are readers from around the world reading this too and I thank you for following our blog. If anyone is going to buy a Glutathione Soap here in the Philippines; do it in supermarkets, drugstores and reputable sites. Not from someone that is really pushy with offering a product.

Ignored the hook, cut the line, detached the sinker

You’d be flummoxed on why these scammers exist and how do they even proliferate with such a shady way of doing business? Where does it start and that’s what we’re gonna talk about so let me show you my experiences to make it clear how they work and how to avoid them.

My first run in with these people is from a simple innocuous message I got from a “friend” in Facebook and that was in 2011. She was asking me if I’d like to join a seminar around Robsinsons Supermarket. But why suddenly? I thought there was no harm in it so I was really considering to go. What do I have to lose yeah? I was just fresh outta high school and trying new stuff.

But I was a lazy bum so I just stayed home without saying a word if I’d really go. The next day I saw her post that there’s a guy in there who was talking to a bunch of people, but I saw a pile of soaps behind him but never bothered to question why. Little did I know that I just dodged a bullet labelled as “networking”.

Fast forward to just a year back; we were looking for a job. A member from a company called “Frontrow” was hiring through a Facebook post that says

LOOKING FOR PART TIMERS

WE ARE HIRING 15-20 PEOPLE IN PULILAN AREA

MUST BE 18-25 YEARS OLD MALE OR FEMALE EARN PHP 2000 A WEEK

PM ME FOR DETAILS

Okay so my pal did send him a message and asked him to invite friends too if possible. Hell we didn’t know the job detail as it only said “Part timers” and I was really getting skeptical but my buddy insisted so we tried it. Again; at Robinsons Supermarket Pulilan.

Meeting time was supposed to be 11 am but the host wasn’t there yet so we took time to play a game of 20 questions. I started to ask them what the seminar is about and they insisted to just wait instead. I had a strong feeling that it was a pyramid scheme so we decided to push them further. I tried to jest with them so I asked “Are you networkers?” And oh ho! They girl I just asked snapped back with a plethora of defenses. I was right.

This is how it looks like and this one is recent

Well shit; they just wasted our time. So much time to spend on another interview rather than that stinkhole. Phe-ew. Thank Goodness we saw right through it.

And the very last run in was with Emma. She was looking for a job just a year ago. I landed a job first so we decided that she could try a home based job. Hello PlanPro Matrix, I surely didn’t miss you.

Emma wanted to try Data Encoding and Captcha Typing to earn some but I really protested against it. She was desperate though so I thought “Alright; if it’s for the benefit of the doubt.” we paid the broker 450 php for a membership fee (Another red flag) and when we tried it. The application won’t work. It needs NET Framework 3.0, and it’s slow as hell. We tried the captcha typing and one mistake had us banned. It was really a scam. Emma felt bad about it so I kept reassuring her that she’ll land a job soon. And she did.

Then it had me thinking; why do people fall for these things? The answer I could come up with is desperation and the high cost of living. Many are unemployed, many wants to earn a living. Problem is some want quick success and it is that naivety or gullibility that gets a victim caught up in their web of deceit.

Most of these recruiters are victims too who just held onto it thinking that eventually they can turn things around. But I do feel sorry for them. The referral and invitation system requires them to sell their souls and humanity and be a persistent and shameless drone. Not gonna mince words here. I know there would be an offence taken.

Wake up networkers! No amount of cognitive dissonance would save you from it. There’s no dignity in trying to dupe another person into joining or selling glutathione soaps.

Yes you might argue with me that you might be selling well, but hey; you’re buying too and it isn’t cheap.

That’s just lazy and unethical business from the one who thought of the scheme.

There’s no real money in it. Your money is just going to the head honcho. You’re working for their sake, not yours.

See; you’re not selling the products. No my good man, you are the product.

And that; my dear readers is what we call the pyramid scheme or networking. A duplicitous type of business that seems harmless to the uninitiated.

Studies say that we Filipinos are very gullible users of the internet, sounds harsh yes;but it is quite true. Why else would our people believe satire and even the promises that tells you of earning a huge sum of money in just a snap? It’s time to wake up and be smarter than this. Learn from mistakes, be investigative.

You want an even better you? Those products won’t do any good. You want to make a living? That is not the answer.

How about you? Any experiences to share?

Pyramid Schemes: Glutathione Soaps, Captchas, Referrals, and Lies I'm sure you've heard of this one before and if you're not sure what it is; let me translate it to a more recognizable name:
