A Data Control Language or DCL is a fraction Structured Query Language (SQL) made use of to control the access to table in a database.

The REVOKE command takes back or cancels privileges (for INSERT, SELECT, UPDATE etc.) on any precise or all tables from various users using the database. The CASCADE option takes back the privileges from the user as well as the chief user who started the permission. In the Grant and Revoke statements also you can apply various keywords such as you can mention a user name , multiple user name or provide access or revoke access from or to all using the keyword ‘ALL’.

In a real-world database-driven situation (such as in an offshore software development corporation) any user receiving the permission on a precise object (such as a table) from a different user "with GRANT option", then that user has the right to set permission on that similar table to a different user standing in as an owner of the table . So now it is upto the owner to whom he has to give the access privileges and from whom the owner van actually revoke the permissions.
