Chapter 7. Analysis: Defining Object Behavior

Chapter 6 showed how to define the system structure by identifying the fundamental objects and classes and their relationships. In this chapter, we define and refine operations and behaviors. There are a number of means for specifying overall object behavior, the most important of these being modeling the object as a finite state machine. Scenario modeling helps you test your behavioral models to ensure that the objects can collaborate to achieve the system responsibilities. The state and scenario models lead to the definitions of class operations required to process the incoming messages and events.
