Upper Level Structure
The upper level of the product structure is the high-level hierarchy of a product, represented by its major areas, sections, zones, or other object designations set by your site. Generally, the upper-level structure is determined early and rarely changes once it has been established. The upper level of the product structure is flexibly designed to accommodate the varied purposes of any site and any type of product. Specifically, the organization of the objects within the upper level of the product structure can be defined according to hierarchical or other relationship requirements.
Upper-Level Objects and Structure Example
WADM configuration management includes a base upper level object type that can be used out of the box. However, you can create any number of upper-level object types and define any configuration of parent-child relationships between them.
For example, in the diagram below, the following objects for the upper level of a product are defined:
Major Area—The highest-level object of the upper level product structure.
Section—Only a section can be a child of a major area. A section cannot be a child of any other object type.
Zone—Only a zone can be a child of a section. A zone cannot be a child of any other object type.
Configuration Item—Since a zone is the lowest object in the upper level, only a zone can be the parent of a configuration item (from the configuration level). A configuration item cannot be the child of any object type other than a zone.
