AVEVA Catalogue : Hierarchy
Hierarchy
Catalogues are constructed as a hierarchy of elements, each element has certain attributes and some may contain further member elements, the complete catalogue hierarchy is displayed below.
All database elements are owned by other elements, therefore elements must be created in a strict order.
The following database elements are common to all catalogue disciplines:
•
WORLD
•
CATALOGUE (CATA)
•
SECTIONS
•
CATEGORIES (optional).
Sections and Categories are administrative elements which allows the segregation of particular types of catalogue data into logical parts of the hierarchy. Sections which subdivide an overall CATA are obligatory; Categories, which subdivide Sections, are optional. A CATA can contain a number of Catalogue Sections. These are of two types: Piping Sections (SECT) and Structural Sections (STSE).
To create a section, refer to Create Section for further information, to create a category, refer to Units for further information.
Some database elements are only applicable to specific disciplines such as table definitions and connections. For more detailed information on the hierarchical structure and the catalogue database, refer to Catalogue Database Structure for further information.
