Week 5 Project Tasks

Now that you have created use-case models for your system, you will continue your system design by completing your class diagram and applying behavioral diagrams.

1. Extend your class diagram by including associations, indicating the object role and multiplicity on each end of your associations. Add any new classes, attributes, or operations that you may not have considered in your Week 3 diagram. Specify the data type and visibility of each attribute.

2. Develop sequence diagrams for two use-case scenarios from your W3 Project.

Justify any assumptions on some of the messages passed between objects.

Clearly indicate what objects are involved in each diagram.

3. Develop activity diagrams for two usecase scenarios from your W3 Project. The use-case scenarios may be the same or different from task 1.
