Overview
The delta event propagation process uses the PeopleSoft
integration broker, the WebSphere(R) MQ
message queue, and the adapter utility XML ODA and XML data handler,
to send business updates from the PeopleSoft application to the
adapter. Event polling is never performed as a part of this process.

The following steps occur during the process:
- You create an XML message definition for each component of interest.
The message structure mirrors the structure of the component.
- When you make and save changes to a component, the changes are
copied to the corresponding XML message definition instance.
- The PeopleSoft integration broker uses the JMSTargetConnector
to publish the XML messages onto the MQ message queue.
- The adapter for PeopleSoft picks up the messages from the MQ
message queue.
- The adapter uses the XML ODA and the XML data handler to construct
a WebSphere business object from the XML message. The business object
reflects the changes that were made to the component within the
PeopleSoft application.
