Glossary Term System Catalog
Definition The data dictionary of a DBMS. The system catalog stores metadata 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 users can query it like any other table.
