Data Warehouse Schema
For the latest version of Commerce Server 2007 Help, see the Microsoft Web site.
The Commerce Server Data Warehouse uses a logical schema to isolate applications from the underlying physical database. The basic structures of the logical schema are the class, data member, relation, and key. You use a meta-model that contains a set of attributes (the metadata) to define these basic structures. You only need detailed knowledge of the logical schema when you extend the schema to store more data in the Data Warehouse.
