EE5805 Java Programming and Applications
The following notes on Use Cases are excerpted from Fowler's "UML Distilled":
1. Use cases are a technique for capturing the functional requirements of a system.
2. Use cases work by describing the typical interactions between the users of a system the system itself. It provides a narrative of how a system is used.
3. A scenario is a sequence of steps describing an interaction between a user and a system.
4. Therefore, a use case is a set of scenarios tied together by a common user goal.
5. An actor isa role that a user plays in the system.
6. But almost all the value of use cases lies in the textual content, and the diagram is of rather limited value.
