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

  - Commerce+ database schema
    The Commerce+ database model was designed for data integrity and optimal performance. Commerce+ provides several hundred tables that store 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.
    - Column data type considerations
      Several column data types are available for you to use when you are creating new database table or columns.
    - Deprecated tables and columns
      If a database table or column is marked as deprecated, then the table or column is outdated by newer constructs. Deprecated sections are supported for reasons of compatibility with an earlier version only. These tables or columns are obsolete or can become obsolete in future versions of HCL Commerce.

  - Dynamic caching
    In general, caching improves response time and reduces system load. Caching techniques are used to improve the performance of World Wide Web Internet applications. Most techniques cache static content (content that rarely changes) such as graphic and text files. However, many websites serve dynamic content, containing personalized information or data that changes more frequently. Caching dynamic content requires more sophisticated caching techniques, such as those provided by the Open Liberty Server dynamic cache, a built-in service for caching and serving dynamic content.
  - Cache-entry elements
    The root element of the cachespec.xml file, <cache>, contains <cache-entry> elements. The WebSphere dynamic cache service parses the cachespec.xml file during start-up, and extracts a set of configuration parameters from each <cache-entry> element.
  - Commerce+ web services
    Commerce+ provides many web services.
  - Utilities
    In Commerce+ utilities are scripts that perform operations such as loading access control policies, loading store data, and cleaning the database of obsolete objects. In runtime environments, run utilities from the Utility server Docker container. In the development environment, run utilities from the bin directory.

    The following URLs relate to the Messaging system.
  - Scheduler URLs
    The server subsystem consists of functions that are associated with URLs that are run by the scheduler.
