    a) DDL (Data Definition Language): It is used to define the database structure such as tables. It includes three statements such as CREATE, ALTER, and DROP.

    Some of the DDL Commands are listed below:

    CREATE: It is used for creating the table.

    CREATE TABLE table_name column_name1 data_type(size), column_name2 data_type(size), column_name3 data_type(size), ALTER: The ALTER table is used for modifying the existing table object in the database.

    ALTER TABLE table_name ADD column_name datatype OR

    ALTER TABLE table_name DROP COLUMN column_name b) DML (Data Manipulation Language): These statements are used to manipulate the data in records. Commonly used DML statements are INSERT, UPDATE, and DELETE.

    The SELECT statement is used as a partial DML statement, used to select all or relevant records in the table.

    c) DCL (Data Control Language): These statements are used to set privileges such as GRANT and REVOKE database access permission to the specific user.
