Commerce+ Transaction Server database schema
The Commerce+ Transaction Server database model was designed for data integrity and optimal performance. Commerce+ Transaction Server provides several hundred tables that store Commerce+ Transaction Server 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.
Data models
Any given database data model displays the relationship among database tables in the schema.
Commerce+ Transaction Server search data model
The Commerce+ Transaction Server search data model shows the relationship between database tables that are related to Commerce+ Transaction Server search.
