Service

The Service layer typically takes care of interacting with external applications: Databases, Remote Web APIs, Message Queues, etc.

Services can be connected and–to provide a good level of flexibility–supports both Inheritance and two types of Composition.

Check out the Connecting Services example to see how a service can integrate and interact with other services.
