The database catalog of a database contains the metadata of all database objects. 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
· Metadata for the objects generated by a user or user group. Among other things, this includes metadata for base tables and view tables.
A user can only access the metadata of another user or another user group if authorized to do so (see User Concept).
