1. Perform a requirements analysis for the Case Study. Express the results using the following artefacts:

    a. A use case diagram for the functional requirements of the entire system, accompanied by:
        i. Short use case descriptions for each use case
    b. A system-wide (non-functional) requirement document.
2. Select the two (2) most essential use cases in the system, and produce full use case descriptions for each one. For each of these two most essential use cases, also produce an activity diagram that expresses the workflows for that use case.

Use Case Realization

3. Develop a domain model for the Case Study. Express your model with a class diagram, showing any inheritance and compositional relationships.

4. For each of the two selected most essential use cases, develop use case realizations showing the sequence of messages involved. Express these use case realizations in separate communication diagrams.

5. For each of the two selected most essential use cases, translate the communication diagram produced for Task 4 into an equivalent sequence diagram.
