Structure of the Catalog Database

Catalogs are constructed as a hierarchy of elements. Each element has certain attributes and some may contain further member elements. The complete Catalog hierarchy is shown in Catalog Database Hierarchy.

Note:
In any discussion of attributes which may appear in the rest of this chapter, the ‘standard’ attributes of TYPE, NAME, OWNER and LOCK will not be mentioned, as these are common to all the elements described below.

In addition, User Defined Attributes (UDAs) and User Defined Element Types (UDETs) may be used with Catalog database elements.
