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 the Catalog Database Hierarchy image.

Note that 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. Refer to the Lexicon User Documentation supplied with Administration for further information.
