About SQL

The Structured Query Language (SQL) is a largely standardized language, which is used for accessing relational databases. It can be divided as follows:

Data Manipulation Language (DML)

These statements are for reading and changing data in database tables.

Data Definition Language (DDL)

These statements are for creating and administering database tables.

Data Control Language (DCL)

These statements are used for authorization and consistency checks.

Here, each database has a programming interface. This programming interface allows the user to access the database tables by using SQL statements. But, these SQL statements in the programming interfaces are not fully standardized. So, you must refer to the documentation of that system for a list of the SQL statements available and also their correct syntax in order to access a specific database system.
