Figure 3–1: The Business Servicing Layer

As you can see, the key components of the Business Servicing interface are Business Entities, Business Tasks, and Business Workflows, which together implement the business logic of an application. In addition, there is a Service Interface for communication with client-side layers of the application.

The "Components of the Business Servicing Layer" section provides more information about these components.
