DCL stand for (Data Control Language) which is the subset of the Structured Query Language (SQL) and also responsible to allows database administrators to configure security access to relational databases. By using that command, we can add and delete database objects, and the Data Manipulation Language which is used to retrieve, insert and modify the contents of a database. The DDL is mainly used for define tables, databases and views etc. and we can also manipulate those existing tables, views etc. Basically, DCL is used to create roles, permissions, and referential integrity as well it is used to control access to database by securing it.
