Introduction: Services modeling

Lessons in this tutorial

• Lesson 1: Import the sample business process model
  
  This lesson shows you how to create a model project and import an existing business process model into it.
• Lesson 2: Create capabilities that represent candidate services
  
  In a services model, a candidate service is represented by a capability. Some capabilities are prioritized and taken forward for further design and eventual implementation.
• Lesson 3: Create service interfaces
  
  In most cases, such as in real-world models, you have many candidate services that you can design and implement, and you typically prioritize them. However, in this tutorial, you design and implement all four candidate services.
• Lesson 4: Create service contracts
  
  In this lesson, you create three service contracts. Service contracts specify additional details about how service interfaces are used and how the operations of the service interfaces are ordered.
• Lesson 5: Create the SchedulingContract Service Contract
  
  You can now create a simple service contract for the SchedulingService service interface; this service does not require a behavior to be created. The service contract contains parts that represent its user and provider that you can use later in the services architecture.
• Lesson 6: Create participants
  
  In this lesson, you create participants in the service model that use and provide the services in the application. Participants can be users or providers of services (or both). The participants interact with each other to implement the automation of the business process.
• Lesson 7: Create the service architecture
  
  The service architecture shows how the participants work together to provide the overall service(s). 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).
