Developing
The topics in the Developing section describe tasks performed by an application developer.
Controller layer
The Controller layer is the conductor of operations for a request. It controls the transaction scope and manages the session related information for the request. The controller first dispatches to a command and then calls the appropriate view processing logic to render the response.
Integrating with back-end systems and external applications
External systems integration is a key feature of the WebSphere Commerce solution. In WebSphere Commerce business logic is enabled for integration and built-in adapters and interfaces are provided for common integration points. Additionally, the WebSphere Commerce integration solution leverages integration standards by using various IBM connectivity solutions.
Distributed Order Management (DOM) integration
DOM integration enhances the shopping flow in the Aurora starter store, while enhancing backend system integration with WebSphere Commerce. This integration provides comprehensive coverage of the order lifecycle across channels, from capture to fulfillment.
Service interfaces used by Distributed Order Management (DOM) integration
The SyncInventoryAvailability, SyncOrder, and ProcessOrder inbound service interfaces are used by DOM integration. The GetInventoryAvailability, ProcessInventoryRequirement, and ProcessOrder outbound service interfaces are used by DOM integration.
