Answer:
SQL is a programming language designed to get information out of and put it into a relational database. Queries are constructed from a command language that lets you select, insert, update and locate data.
Thus, a visual programming tool for developing database-enabled applications may have an appealing, object-oriented graphical interface. But once the programming is done, the system will convert all the underlying database calls and commands into SQL. This simplifies the integration of front-end and back-end systems, especially in multi-tiered client/ server applications.

SQL (Structured Query Language) is a programming language used to manage data stored in relational databases, which store structured data in tables. Its syntax is easy to read.so it's easy to pick up on even if you're completely new to programming, and it's even useful for non-technical careers.
1.SQL can execute queries against a database
2.SQL can retrieve data from a database
3.SQL can insert records in a database
4.SQL can update records in a database
5.SQL can delete records from a database
6.SQL can create new databases
7.SQL can create new tables in a database
8.SQL can create stored procedures in a database
9.SQL can create views in a database
10.SQL can set permissions on tables, procedures, and views.

Vignesh /what is sql?
Answer :
Structured Query Language (SQL) is a standard data-oriented language which is primarily used to store, retrieve and manipulate data using simple code snippets, called queries, in an RDBMS (relational database management system).
The data is stored in the RDBMS in a structured way, where there exist relations between the different entities and variables in the data. These relations are defined by the database schema which does not only specify the relation between various entities but also the organization of data associated with those entities in the database.

Question: What is SQL?
Answer: SQL is one of system language of data. SQL is the short form of the "Structured Query Language". It is used to communicate with a database, which is the standard language for relational database management systems. Structured Query Language (SQL) is a specialized language for creating, updating, deleting, and requesting information from database.
Structured Query Language contains Five Major Functions.
Those are following below:
1. Data Definition Language. - Create, Alter, Drop
2. Data Manipulation Language. - Insert, Update, Delete
3. Data Control Language. - Grant, Revoke
4. Data Retrieval Language and - Select (Getting the data)
5. Transaction Control Language. - Commit, Rollback
Those are the major functions happening in SQL.
1. Data Definition Language - (DDL)
Data Definition Language is the primary function of SQL. In this can create the table for the data.
For Example:- I'm Working as Professor in the Department of MBA. I should collect the students data and store them. The management requested the students database with individual profile. Now I using the SQL I can collect and store the data.
So The initial stage I Create the Table, which contains rows and columns.
a. Create - I Create the table with heading of Student_Table by using 1 row and 2 column of date ID, Name.
Using Comment - Create table Student_Table ( id int, Name Carchar(100))
b. Alternate - I forgot the another data of the students or I should add the more data. I can add additional data of Age.
Using Comment - Alter table Student_Table add column age int
c. Drop - I don't want the data. The students are completed their Degree. so I don't want their data in current database. So I want to delete them.
Using Comment - drop table Student_Table
2. Data Manipulation Language - (DML)
Data Manipulation Language is the secondary function in SQL. In primary Function (DDL) can created the table and Stored the data. In DML can insert the data, update the data and delete the data.
For Example: Same Scenario From DDL. I want to collect the data, so I created the table.
a. Insert - So now I insert the data of student of 1 in ID and Ganesh In Name and 22 in Age Column.
By Using Comment - Insert into Student_Table ( ID, Name, Age) Values ( 1, 'Ganesh',22)
b. Update - Oops sorry I mistakes in Ganesh's data. His age is 23 but I entered as 22. so I want to change it, and update it.
By Using Comment - Update Student_Table set age=23 where id = 1
c. Oops one student was dropped out from the college. I want to remove his name from Student_Table.\
By Using Comment - delete from Studnet_Table
3. Data Control Language - (DCL)
Data Control Language is Tertiary Function. It is the Optional or permission type function. In this yes or no, Come and Go Type Function.
In this the collected data can access or not for the Person.
For Example: Same Scenario from DML. I Collected from student and stored in Database. Now Someone can see that data. So I should give access for that person.
a. Grant - I grant the permission to the student. I Give the Access for the date to student Ganesh.
By Using Comment - Grant insert on Student_Table to ganesh
b. Revoke - I want to cancel the access to Ganesh to see the data.
By Using Comment - Revoke insert on Student_Table to ganesh
4. Data Retrieval Language - (DRL)
Data Retrieval Language is the final function on the data in SQL. In this can use the data.
For Example: Same Scenario from DCL. I collected the data and stored the data everything done in data. Now I want to use the data.
a. Select - In this I want to use the data. So I Select the data.
BY Using Comment - Select * from student_table
5. Transaction Control Language - (TCL) - Commit, Rollback
Transaction Control Language is the function happened by the user. Every function happened and one by the user. But in this Third party or Third person will involved.
For Example: Same Scenario From DRL. I selected the data and I want to share the data to 100 people.
a. Commit - I Would like to share his details to 100 companies for work.
b. Rollback - I Want to share the details to 100 companies. But unfortunately in between Power is gone. So I Get back, (i.e) undo the message. I cancelled the messages. For Cancellation Using Rollback Comment.
