Lesson 7: Create the service architecture

This content applies to version 7.5.4, or later. The service architecture shows the design of the application in a composite structure diagram. This diagram provides the overall view of the system and how the participants are structured and connected to work together to provide the overall purchasing service. It also shows how each participant plays a role in the relevant service contracts so you can document and verify that the underlying constraints are honored. It gives you a high-level view of your services oriented architecture and design, making it easier to more accurately explain it to others (such as developers who will implement it).
