Guidelines when using Business Object Document-style Web services for back-end integration

Follow these guidelines when using Business Object Document-style (BOD-style) Web services for back-end integration.

• Only a WebSphere Commerce service module should use its external facade client for outbound requests. For example, only the Order service module should use the order external facade client. If a client application or another service module requires order information, the default order facade client should be used to make a service request to the WebSphere Commerce order service. The WebSphere Commerce order service would then make an outbound request if necessary.
• Using InsertMore commands:
  • Use InsertMore commands to retrieve data from an external system and include the data in a response.
  • Try to batch the external system request into one request and merge the result set back together. See Including change control information in the response of a Get service for a sample implementation.
