Creating composite transactions using business proxies
Composite transactions allow you to group related business transactions that should be run as a single unit of work.

The default com.dwl.base.requestHandler.DWLTxnBP business
proxy handles the three types of IBM® InfoSphere Master Data Management transactions: Search, Inquiry,
and Persistent. The business proxy's main function is
to delegate the transaction to the appropriate controller to execute
in the Request framework, based on the transaction name. This business
proxy has very little business logic except to detect the type of
transaction.
Customized business proxies can be implemented to handle addition business logic before delegating the transaction to the controller. This section describes customizing a business proxy so that multiple transactions are triggered at the business proxy level to fulfill a business requirement.
