All Teradata Vantage sites should have at least one user with clearly defined administrative duties.
Teradata recommends that you divide administrative duties between the security administrator and the database administrator, regardless of the number of administrators at your site.
User DBC should create both the database administrator and security administrator users, and should allocate DBC disk space that is not needed for system functions to the administrative users. Then the administrative users can create lower level administrators and other database users, and allocate space to them.
When administrators create users and databases, a hierarchical relationship results.
DBC directly creates the security administrator (A) and database administrator (B) users. DBC is the immediate owner (parent) of A and B, and owns everything in the hierarchy.
- A is the immediate owner, or parent, of C and D.
- C is the immediate owner, or parent, of F.
The database administrator (B) creates database (E). B is the immediate owner of E.
Owners have implicit privileges on the objects they own. See Ownership Privileges.
