The database catalog of a database instance consists of metadata in which definitions of database objects such as Basis tables, view tables, synonyms, value ranges, indexes, users, and user groups are stored.
The database catalog is made up of the following sections:
·
Information
about the installation of the database system and metadata with the
definitions of users and user groups
This part is not assigned to any user or any user group.
·
Metadata for
the objects that have been created by a user or a user group
This includes metadata about basis tables and view tables.
A user can only access the metadata of another user or another user group if authorized to do so. See also: User Concept
