Chapter 10. Modeling Message-Based Behavior with Interactions
discusses the use of sequence diagrams to represent the interaction between parts of a block as a sequence of message exchanges. The interaction can be between the system and its environment or between the components of a system at any level of a system hierarchy.
This chapter discusses the use of sequence diagrams to model how parts of a block interact by exchanging messages.
In Chapter 9
, behavior was modeled using activity diagrams to represent a controlled sequence of actions that transform inputs to outputs. In this chapter, an alternative approach to representing behavior is introduced. This approach uses sequence diagrams to represent the interaction
