The Data Model includes entities from the views and
entities created in the model.
- Entities from Views - For details on these entities,
see the topic, IBM Sterling Warehouse Management System Business Intelligence Views.
- Entities
Created in the Catalog - When a normalized database, typically represented
as a star model, is modeled, it is denormalized in the model to allow
multiple joins in the same tables. That is, a star model is expanded
into a snowflake. Some of this denormalization is done in the YNA
views for commonly joined tables, such as YFS_PERSON_INFO. Other entities
have been duplicated in the Data Model.
