The primary system user, DBC, is the owner or parent of all users, databases, and other objects in the database. By default, user DBC has all privileges for interacting with the database, and can grant access privileges to lower level users.
- All available SQL Engine-managed disk space
- Data Dictionary system tables
- System views that allow retrieval of data from the underlying system tables
The primary active function of user DBC is to initially create the administrative users, transfer the ownership of most available disk space to them, and grant them privileges in the database. Administrative users should then perform most administrative functions under their own user names and not as DBC.
