  3. 6. The System Catalog

  4. Catalogs for Relational DBMSs • “Minidatabase” that stores the schemas (descriptions) of DBs; that is the metadata or the “data about the data” • relation names, attributes names, attributes domains (type and size) • integrity constraints (primary and foreign keys) • views (name and definition) • indexes and storage structures (B+ tree) • security and authorisation information • names of users authorised to use the DBMS, data items that each user can access and how it can be accessed (insert, update, delete, read) • statistics about relations and indexes • index size, cardinality, etc • Catalog information is stored in relations (system objects) accessible to authorized users • Catalog relations can by queried using SQL

  5. Data Dictionary (Repository) • Stand-alone package used for information resource management • Mainly used by the designers, users, and administrators of a computer system • Passive or active
