Create the principal database administrator, user DBADMIN (or the name your site uses), and grant space and privileges to the user before proceeding with database implementation. User DBADMIN can then create databases, tables, users, and other objects in the space it owns.
For larger systems, you may find it useful to create additional administrative users to share database administration duties. See the sections beginning with “Administrative Users” in Teradata Vantage™ - Advanced SQL Engine Security Administration, B035-1100.
