 Database User 

Database users can connect to a database instance, execute SQL statements, and work with database objects such as tables, views, and indexes.

To manage the database instance (for example, make backups or recoveries), you need a Database Manager operator. The database system administrator is the only database user that can log on to the Database Manager as well.

The database system uses several different database user classes. The database user class that a database user belongs to defines which database operations that user is allowed to execute.

The database user classes are as follows:

·        Database system administrator (SYSDBA user)

·        Database administrator (DBA user)

·        DOMAIN user

·        RESOURCE user

·        STANDARD user

Database users can be grouped into user groups. The database system supports a role concept.

Administration of Database Users

For the administration of the database users, use the SQL statements for user authorization.
