Overview of the InfoSphere MDM XML interface

Transactions are processed through transaction-specific methods on each of the controller interfaces.

The controller interfaces are as follows:

• Add and Update transactions are processed through the Txn controller.
• Get and Search transactions are processed through the Finder controller.

The external user does not access these methods directly. Default transaction messages are sent as XML messages to the DWLServiceController in DWLRequest and DWLResponse Framework components, which invoke the appropriate controller method and return the response. In this way, the XML interface serves as a single point of entry for InfoSphere® MDM.
