Asynchronous agnostic Composition Controller
The block diagrams shown previously present the complete solution that consisted of the
order management part (non-agnostic task-orchestrated services together with entity ser-
vices), encompassing the following generic parts as well:
• Business delegates as service brokers, both synchronous and asynchronous (cur-
rently we will focus on asynchronous), fulfilling the role of an agnostic Composi-
tion Controller
• A Service Broker facade, responsible for wrapping an inbound Order message into
a message container
• An Inventory Endpoint in the form of Execution Plan Lookup Service, as we have
only EPs in our Metadata Repository for the time being
• A Task Router that is presented as a mediator for a synchronous service broker
The next step after you're done with drawing a comprehensible solution block diagram is
presenting detailed sequence diagrams, covering all aspects of the components' runtime be-
havior. Needless to say that it can only be done with close cooperation with the developers.
Here, we would like to present the complete sequence diagram with focus on Service
Broker's activities shown as follows:
