ch7 True/False Indicate whether the statement is true or false. ____ 1. A use case diagram is a convenient way to summarize system activities. ____ 2. In all use cases, the actor is always inside the automation boundary of the system. ____ 3. An actor in a use case analysis is the person who is actually interacting with the computer system. ____ 4. Use cases always focus on the business processes. ____ 5. An event table emphasizes the automated part of the system. ____ 6. Because use cases are usually initiated by external actors, temporal and state events are often overlooked if the analyst does not carefully identify all events. ____ 7. An activity diagram can be used to support any level of use case descriptions. ____ 8. Temporal events cannot be initiated manually. ____ 9. Activity diagrams are not helpful in developing system sequence diagrams (SSDs). ____ 10. In the object-oriented approach to systems development, the flow of information is achieved by sending mes- sages either to and from actors or back and forth between internal objects. ____ 11. In an interaction diagram, messages are sent and received by individual objects, not by classes. ____ 12. In a system sequence diagram (SSD), the only object included is one representing the entire system. ____ 13. In a sequence diagram, a message is considered to be an action that is invoked on the destination object. ____ 14. Use cases can be described in detail with narrative descriptions or activity diagrams. ____ 15. Activity diagrams cannot be used to describe processes that involve automated system activities. ____ 16. State machine diagrams can be considered either as an analysis tool or a design tool. ____ 17. Actors can be systems or other devices that receive services from the system. ____ 18. In a use case diagram, more than one use case may use the services of a common subroutine. ____ 19. Each use case may have only one scenario. ____ 20. A note can be added to any UML diagram to add explanations. ____ 21. All problem domain classes require a state machine diagram. ____ 22. Each unique state in a state machine diagram has a unique name. ____ 23. A communication diagram is an interaction diagram. ____ 24. A verical dashed line on an activity diagram represents the object lifeline. ____ 25. The exception conditions from a use case description can also be documented using an activity diagram. ____ 26. The heavy bar in an activity diagram is always used to represent concurrent paths. ____ 27. The true/false condition on a message is evaluated after the message is sent to test if the destination object should accept the message.
