Each database requires at least one person to administer it, called Database Administrator (DBA).

Some DBA tasks are:

• Install the software (Microsoft SQL Server) and also upgrade the system.
• Allocate additional storage spaces taking into account user needs.
• Create the necessary logical objects (tables, views, indexes, etc.) as soon as the “application developers” have completed a new application.
• Create users and grant them the necessary privileges.
• Ensure database security.
• Check and monitor user access to the database.
• Monitor and optimize database performance.
• Plan the most suitable backup and recovery strategy for the database.
