Service components implement the business logic or processing rules of the SOA composite application. A Mediator service component routes data through an SOA composite application. Using the Mediator service component, you create routing services and rules for them. A routing service is the key component for moving a message from entry point to exit point in an application. The rules determine how a message instance processed by the routing service gets to its next destination.
You add a Mediator service component to an SOA composite application by dragging it from the Component Palette into the Components section of the SOA Composite Editor.
This invokes the Create Mediator dialog for defining the type of Mediator service component to create (for example, to route data synchronously, to route data asynchronously, or to define an interface at a later time).
