system catalog

(database)
The data dictionary of a DBMS. The system catalogue stores meta-data including the schemas of the databases. It is a mini-database, and is usually stored using the DBMS itself in special tables called system tables. It maybe referred to as being "on line", as it is active, and can be queried by users like any other table.
