The outbound OTD in the Sun Master Patient Index project is based on the object structure define in the Object Definition file. The OTD is used for distributing information that has been added or updated in Sun Master Patient Index to external systems. It includes the objects and fields defined in the Object Definition file plus additional SBR information (such as the create date and create user) and additional system object information (such as the local ID and system code). If you plan to use this OTD to make the master index application data available to external systems, you must define a JMS Topic in the master index Connectivity Map to which the master index application can publish transactions.
