SQL (Structured Query Language)

SQL is a complete language with its own DDL and DML components:

A. Data Definition Language

    
    It is used to define relation schemes by providing instructions. Among other things, you can delete relations and create indexes.

B. Interactive Data Manipulation Language
    
    It is capable of inserting, deleting, and updating tuples in a relation.

C. Embedded Data Manipulation Data

    SQL is incorporated using the embedded form of the DML statements into programs written in different programming languages
