The Teradata Vantage Data Dictionary is composed of tables and views primarily in database DBC. The dictionary also includes tables and views from in a number of other system databases (for example, Sys_Calendar, TD_SYSFNLIB, SYSUDTLIB, SystemFE, and SYSUIF), and from other databases (for example, TDMaps and SQLJ).

Dictionary tables contain metadata about system objects, privileges, events, and usage. These tables are reserved for system use, and should not be accessed directly. Users can retrieve data from tables indirectly, by accessing predefined Data Dictionary views. The database administrator can limit user access to dictionary views on a user-by-user or role-by-role basis.
