WebSphere Commerce database schema
The WebSphere Commerce database model was designed for data integrity and optimal performance. WebSphere Commerce provides several hundred tables that store WebSphere Commerce instance data. To maintain data integrity, and to ease maintenance referential integrity, constraints are widely used in the database model. Indexes are used carefully on tables to avoid over-indexing and to provide a good balance between data retrieval and data manipulation activities (insert and update). The business rules are implemented at the application level rather than by using database trigger. Triggers, however, are used to facilitate data staging and optimistic locking. A limited number of SQL-based database stored procedures are used for data intensive activities.
Any given database data model displays the relationship among database tables in the schema.
The system data models show the relationship of database tables used for WebSphere Commerce system functions.
The Mobile device data model shows the relationship between database tables that contain information about mobile (pervasive) device options within the system.
