Introduction : How AVEVA E3D™ Data is Stored

Despite the huge power and potential of AVEVA E3D™, the database is structured in a very simple and logical form. The database is hierarchical, a tree like structure, as illustrated below.

Note:

The hierarchy below illustrates the (simplified) MODEL database hierarchy, but the SCHEMATIC, ENGINEERING, CATALOGUE, PADD, ISOD, LEXICON and PROPERTIES databases also have a hierarchical structure.

In this hierarchical structure all the database elements are owned by other elements, with the exception of the WORLD. Elements that are owned by another element, e.g. a ZONE is owned by a SITE, are said to be members of the owning element, e.g. The ZONE is a member of the SITE.
