Data Warehouse Schema
The Commerce Server 2002 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. A meta-model containing a set of attributes (the meta-data) is used to define these basic structures. Detailed knowledge of the logical schema is only needed when extending the schema to encompass a third-party data structure.
This section contains:
- Data Warehouse Classes. Lists in alphabetical order the conceptual (logical) classes in the Data Warehouse.
- Data Warehouse Meta-model. Describes the meta-model used to define the classes, data members, class relations, and class keys of the Data Warehouse.
- Physical Schema. Describes the logical-to-physical mapping of the conceptual data to the underlying data store.
