Yes time is a factor that can be modeled but the way the instructor is going about it seems a stretch to me because time itself does not care what happens when, it just is. Use case diagrams show the expected behavior of the system. ANS = inclusion relationship allows one use case (base use case) to include functionality from another use case (include use case); this is not a functional decomposition but rather just and include; noted as dashed line arrow <>; the base use case may have dependencies on the include use case; [10] Apart from a base and extending use case which two other pieces of information might an extension relationship have? ANS = uc; model element type is either package or block; Use case diagram = frame represents package or block; content of diagram has set of actors and use cases with relationships; header has this form: uc [model element type] model element name [diagram name], [2] Which types of model elements can a use case diagram represent? • Use case diagrams and sequence diagrams are used to describe the interactions between users and systems in the system being designed. 6. ANS = package or block. A use case describes how a user uses a system to accomplish a particular goal.
