Database catalog
From HandWiki
Short description: Metadata of database objects
A database catalog of a database instance consists of metadata in which definitions of database objects such as base tables, views (virtual tables), synonyms, value ranges, indexes, users, and user groups are stored.[1][2] It is an architecture product that documents the database's content and data quality.[3]
Standards
The SQL standard specifies a uniform means to access the catalog, called the INFORMATION SCHEMA, but not all databases follow this, even if they implement other aspects of the SQL standard. For an example of database-specific metadata access methods, see Oracle metadata.
