In services models, ServiceChannels connect consumers and providers and therefore define
the coupling in the system. They isolate the dependencies between consuming and providing participants to particular
Request/service interaction points.
This figure illustrates a Manufacturer service Participant that assembles a number of other Participants
necessary to actually implement a service as a deployable runtime solution. Manufacturer provides a purchaser service
that it delegates to the purchasing service of its orderProcessor part. ServiceChannels connect the Requests to the
Services the OrderProcessor needs in order to execute.
