Solution

The various languages that are used in a Database Management System (DBMS) are:

  1. Data Definition Language (DDL): This is used to define the database structure or schema. It is used to create, alter, and drop the database objects.

  2. Data Manipulation Language (DML): This is used to retrieve, store, modify, delete, insert and update data in a database.

  3. Data Control Language (DCL): This is used to control the visibility of data. It includes commands like GRANT and REVOKE which mainly deals with the rights, permissions and other controls of the database system.

  4. Transaction Control Language (TCL): This is used to manage different transactions occurring within a database. It includes commands like COMMIT, ROLLBACK, etc.

The Transaction Definition Language is not typically listed as a separate language used in a DBMS.
