A hierarchy represents a set of members and their positions relative to one another. From the top of the pyramidal structure to the bottom, the members are progressively more detailed. User hierarchies are defined to represent a hierarchy that has meaning to the user or application.
In ADOMD.NET, the Hierarchy can represent both parent-child hierarchies and user hierarchies. The HierarchyOrigin property is used to differentiate between the hierarchy structures.
