Chapter 7: Creating Sequence Diagrams
A sequence diagram lets you model and visualize interactions between different actors or objects in a system, as well as the order of those interactions. A sequence diagram focuses on one scenario and captures the system behavior for that duration. This type of diagram will let you model how different actors interact within a system, which messages are being sent between them, and in which order those messages are sent. Sequence diagrams will help you to describe the functionality of a system in a way that is easy for a reader to understand. They also assist in verifying that a scenario will be handled by the design. Another strength of sequence diagrams is that even first-time readers without prior knowledge of them can usually understand the meaning of a diagram without much explanation.
In this chapter, we will look at the following topics:
- The core elements of a sequence diagram
- How to handle different paths of events in sequence...
