Reference Data Model

The Reference Data Model contains the entities (Tariff plan, Product, etc) for a carrier in a communications organization. These entities translate into dimensions (and hierarchies), which provide the essential structure for the Aggregate and Derived data models.

(Note: Reference entities are also used in the SELECT clauses of materialized view creation.)

OCDM provides the following reference entity categories. These categories -- and entities for each -- are shown below. (Note: Although not shown here, a Time category and it's associated entities are also included in the Reference Data Model.)

• Network Element
• Product, Package & Tariff Plans
• Access Method
• Account
• Carrier
• Customer & Privacy
