Authorizations

After the logon data has been authenticated, a user can, within the framework of his or her authorizations, access data in the database instance and use database tools.

The MaxDB database system has the following types of users:

·        Database System Administrator (SYSDBA User)

The database system administrator has comprehensive authorizations for access to the database instance and database tools.

·        Database User

Database users access the data in the database instance using SQL statements. The user class determines what authorizations a user has.

·        DBM Operator (Database Manager Operator)

DBM operators manage database instances with the database tool Database Manager. A DBM operator’s server authorizations determine what authorizations he or she has.

For more information about server authorizations, see Concepts of the Database System, Server Authorizations for the DBM Server.
