One of the more common tasks of the DBA is the creation of the database user. Each database user is assigned a unique username. Users will log into the database using that username, and having logged in, users can issue various database SQL statements to create objects, query objects and manage the database.

In this section we will cover the creation of Oracle users with the Oracle create user command. We will then look at the alter user command to administer users and finally we will address the drop user command which allows you to drop users from the database.
