Object-Oriented Analysis Phase 1. The object-oriented approach considers the _. A. data and actions B. data only C. functions only D. behavior only E. interactions only 2. In finite State Machines the emphasis is on: A. data and actions B. data C. actions D. data actions and interactions E. interactions 3. Using the object-oriented approach, the emphasis is on: A. data primarily B. actions primarily C. neither data nor actions D. data and actions but asynchronously E. data and actions simultaneously 4. Why has it been suggested that it is easier to build and maintain large systems using an Object-oriented approach? A. Development and management are easier as objects are essentially independent components. B. Objects are reusable. C. Structured systems tend to look either at actions (e.g. procedures and functions) or data only, while, in contrast, Object-Oriented techniques consider both. D. One approach is not necessarily better than another - its a matter of picking horses for courses. E. The Object-Oriented approach avoids the build-and-fix model mentality. 5. The advantage of using the Object-oriented approach compared to the Structured approach is: A. fewer faults are detected. B. fewer change requests are made during development and maintenance. C. adaptive and perfective maintainability increased significantly. D. improvements in usability E. all of these 6. The Object-Oriented paradigm offers major advantages over comparable methods. Which of the following statements is false? A. The use of Object-Oriented has lead to overall improvements with no loss in performance. B. The Object-Oriented paradigm is the ultimate answer to all software engineering problems. C. Adaptive and perfective maintainability increased significantly using the Object-Oriented paradigm . D. Analysis is a process of stepwise refinement, so sometimes the emphasis is on data and sometimes on data but overall they are given equal importance. E. All of these are true. 7. UML presents a: A. methodology B. method C. set of techniques D. notation E. all of these 8. Object-Oriented analysis is best classed as a(n) _ technique. A. formal B. informal C. semiformal D. behavioural E. procedural 9. A scenario is an instance of a(n) A. reuse B. encapsulation C. use case D. interaction (i.e. message passing) E. inheritance 10. A class diagram is analogous to a(n) A. functional decomposition B. finite state machine model C. use case D. interaction (i.e. message passing) E. entity relationship diagram 11. A state diagram is analogous to a(n) A. functional decomposition B. finite state machine model C. use case D. interaction (i.e. message passing) E. entity relationship diagram 12. A scenario is: A. one particular set of interactions between specific objects and users. B. a generic description of the overall functionality of a product. C. the overall interaction between the classes of the software product and the actors (users) of the product. D. a description of the actions performed by or to each class or subclass. E. a description of the classes, their attributes and behaviours. 13. A method for determining the classes during Object-Oriented analysis is to: A. deduce them from the Use Cases. B. determine them using CRC cards when the developers have domain expertise. C. extract them from the problem definition and its accompanying constraints. D. all of these E. none of these. i.e. This is a step best left until the design stage. 14. Abstract nouns rarely end up corresponding to classes. Instead they are frequently: A. actions or behaviours B. outside the scope of the problem boundary C. instances D. methods of classes E. attributes of classes 15. In UML an open triangle denotes: A. message passing B. inheritance C. instantiation D. aggregation E. association 16. CRC stands for Class Responsibility _. A. Classification B. Categorisation C. Communication D. Collaboration E. Client 17. Using CRC cards, the Responsibilities correspond to the: A. attributes B. functions C. interactions with other classes D. the classes themselves E. instances 18. The strength of CRC is that it is useful in: C A. determining the classes without the need for a great deal of domain knowledge. B. developing the product using Cleanroom techniques. C. completing the analysis process and making sure everything is correct. D. none of the above. i.e. this approach is superseded by the use of CASE tools. E. all of the above 19. If an item possesses a state then it should probably be modelled as a(n): A. state variable B. instance variable C. class D. method E. sub-class 21. A strength of using CASE tools is that: A. a change in the underlying model is reflected in all o
