The Task Overview and Edit use case (UC008) is part of the task management subsystem of the XDM application. In the example in this chapter, we will only build the UC008 use case from this subsystem. Later in this chapter, we will build the scheduling subsystem, again by implementing only one use case (Person Task Timeline, UC104). Finally, we will integrate these two subsystems together in a master application. In a real-life application, each subsystem will, of course, contain more than these simple one-screen use cases.

In this section, we will briefly go over the building of the Business Components and screens—you can refer back to Chapter 1, The ADF Proof of Concept, for more detailed descriptions.
