Data is an important asset of the company. There are many cases where a company's down fall is resulted from a loss of data. All Enterprise databases require some form of security. Security ensures that unauthorized users should not have access to data. However, there are many users that require access to the database.

Assume that the company has hired you as a Database Administrator, discuss and demonstrate how you will enforce data security and maintain data usability using DCL (Data control language) commands such as GRANT, DENY and REVOKE.
