1. （D） is the program code blocks that are reusable, and can provide interfaces to complete the specific functions。A. Modula B. Function C. Use Case D. Component2. In class diagram，“#” symbols the visibility of（B）A. Public B. Protected C. Private D. Package3. Sequence diagram is consists of actor，lifelines，activation bars and（B）.A. relationships B. messages C. use-cases D. entities4. Which symbol can represent package diagram？（A）A. B. C. D. 5. Which one of the tasks are not included in the decision analysis phase? （C）A. Analyze candidate solutionB. Compare candidate solutionsC. Identify and express requirements D. Recommend a system solution6. In activity diagram the actions are partitioned by （B）. Each group represent a specific class, person or department which has the responsibility for the actions in the group.A. join B. swimlane C. fork D. merge7. The PIECES framework was developed by James Wetherbe as a means to classify problems. Which one of the categories is not included in PIECES? （C）A. Performance B. Service C. Change D. Efficiency8. Which one of the following attribute naming is incorrect? （A）A. *BirthDay:DateB. #studentBirthDay:Date=1999-10-21C. price:float=12.01R/WD. +studentName:String=“Min Zhang”9. Which of the following notations are not typically involved in activity diagram? （D）A. Actions B. Merge C. Decision D. Inheritance10. （B） is a system development strategy that emphasizes speed of development through extensive user involvement in the rapid, iterative, and incremental construction of series of functioning prototypes of a system that eventually evolves into the final system.A. Model-Driven Development StrategyB. Rapid Application Development StrategyC. Commercial Application Package Implementation StrategyD. Hybrid Strategies11. How many kinds of notations can be used to represent interface in UML? （A）A. 2 B.4 C.6 D.81. The factoring of the lifetime of an information system into two stages, systems development and systems operation and maintenance 。2. In sequence diagrams, lifelines are the dashed vertical lines extending downward from the actor and system symbols, which indicate the life of the sequence.3. The three main types of object classes used in object-oriented design are _entity_ classes、_interface_ classes and control classes.4. The relationship of _composition_ in class diagram is an aggregation relationship in which the “whole” is responsible for the creation and destruction of its “parts”. If the “whole” were to die, the “part” would die with it.5. You are a system analyst and have been asked to facilitate the analysis and evaluation of several candidate system solutions for their feasibility. You will typically use four sets of criteria for your evaluation: technical feasibility , operational feasibility, economic feasibility and schedule feasibility.6. _ Activity diagram _ can be used to graphically depict the flow of a business process, the steps of a use case, or the logic of an object behavior.7. Applied to an object, both _attributes_ and behaviors of the object are packaged together. They are considered part of that object.8. The _ requirement analysis phase defines and codifies the business requirements for the new system. 9、Sequence Diagram is composed of actor, object, _lifelines_, activation bars, input/output _messages_ and frame.10. Whereas systems analysis emphasized the business problem, system design focuses on the technical or _ implementation _ concerns of the system.
