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.

Initially, user DBC contains:
  • All available Analytics Database-managed disk space
  • Data Dictionary system tables
  • System views that allow retrieval of data from the underlying system tables
Because user DBC automatically has a wide range of database privileges, you should restrict access to the user DBC password to only the most trusted administrative personnel.

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.

Never alter the database privileges for user DBC. If you change DBC privileges, you may cause installation, upgrade, maintenance, archive, or other procedures to fail, and require Teradata Support Center assistance to correct the problem.
