The Teradata Data Dictionary is composed of tables and views primarily in database DBC but also in a number of system databases (for example, Sys_Calendar, TD_SYSFNLIB, SYSUDTLIB, SystemFE, and SYSUIF) and in other databases (for example, TDMaps and SQLJ) that users can retrieve. Tables are reserved for system use and contain metadata about system objects, privileges, events, and usage. Users can retrieve frequently used data from tables via pre-defined views. The Teradata database administrator determines the set of views available to a user.
