Based on Dewey’s interview with Peri and the requirements description in her report, as well as your own experience using library services, use UML to answer the following questions.

1. Draw a use case diagram to represent actors and use cases in the system.

2. For each use case, describe the steps (as we did to organize the use cases).

3. Describe scenarios for the steps. In other words, create a patron and write up an example of the patron as he or she goes through each step.

4. Develop a list of things.

5. Create sequence diagrams for use cases based on steps and scenarios.

6. Complete the class diagram by determining relationships between classes and defining the attributes and methods of each class. Use the grouping thing called package to simplify the class diagram.

As Dewey Dezmal enters the high-ceilinged, wood-paneled reading room of the Ruminski Public Library, a young woman, seated at a long, oak table, pokes her head out from behind a monitor, sees him, and stands, saying, “Welcome. I’m Peri Otticle, the director of the library. I understand you are here to help us develop our new information system.”
