第2题：

The purpose of the systems analysis phase is to build a logical model of the new system.The first step is（71），where you investigate business processes and document what the new system must do to satisfy users. This step continues the investigation that began during the（72）. You use the fact-finding results to build business models，data and process models，and object models. The deliverable for the systems analysis phase is the（73），which describes management and user requirements，costs and benefits，and outlines alternative development strategies.The purpose of the systems design phase is to create a physical model that will satisfy all documented requirements for the system. During the systems design phase，you need to determine the（74），which programmers will use to transform the logical design into program modules and code. The deliverable for this phase is the（75），which is presented to management and users for review and approval.

A.system charter
B.system scope definition
C.system blueprint
D.system requirements document

答案：B
解析：
翻译：系统分析阶段的目的是建立新系统的逻辑模型，第一步就是进行（71），调查业务流程并记录新系统必须做哪些以满足用户需求。这一步是（72）的延续，可以使用调查结果构建业务模型，数据和流程模型以及对象模型。系统分析阶段的可交付成果是（73），它描述了管理和用户要求，成本和收益，还有可替代的方案。系统设计阶段的目的是创建一个能够满足系统所有需求文件要求的物理模型。 在系统设计阶段，需要确定（74），程序员通过系统过程模型把逻辑设计转换为程序模块和代码。该阶段的可交付成果是（75），提交给管理层和用户审查和批准。（73） A．系统章程B．系统范围定义C．系统蓝图 D．系统需求文件
参考答案：（73）B

第6题：

A customer would like to convert their existing IBM System Storage DS8100 to a DS8700 to gain more capacity. During the TDA review the impact on the running production environment during conversion is discussed. Which of the following must be considered?（）

A. DS8000 model conversions are generally non-disruptive

B. a model conversion from DS8100 to DS8700 is disruptive

C. the DS8100 base frame needs to be sent back to the factory for upgrade

D. during model conversion the logical configuration can be kept, but the system must be rebooted


参考答案：B

第7题：

Many of the activities performed during the preliminary investigation are still being conducted in ____, but in much greater depth than before. During this phase, the analyst must become fully aware of the ____ and must develop enough knowledge about the ____ and the existing systems to enable an effective solution to be proposed and implementeD．Besides the ____ for process and data of current system, the deliverable from this phase also includes the __请作答该选项__ for the proposed system.

A.hardware anD.software specification
B.system performance specification
C.formal requirements definition
D.general problem statement

答案：C
解析：
初始调查阶段的许多活动仍然会在分析阶段进行，但会比前面更为深入。在这个阶段，分析师必须认识到根本性问题，并且必须获取足够的关于业务环境和现有系统的知识，以便提出和实现一种有效的解决方案。除了现有系统过程与数据的逻辑模型外，这一阶段的交付物还包括所建议系统的形式化需求定义。

第8题：

Models drawn by the system analysts during the process of the structured analysis are(72).

A.PERTs

B.EMV

C.UMLs

D.DFDs


正确答案：D
题目翻译：在结构化系统分析过程中绘出的模型图是DFD图。数据流图（DataFlowDiagram，DFD）是一种能全面地描述信息系统逻辑模型的主要工具，它可以用少数几种符号综合地反映出信息在系统中的流动、处理和存储情况。DFD由数据流、加工、数据存储和外部实体4个要素构成。外部实体是指存在于软件系统之外的人员或组织，它指出系统所需数据的发源地和系统所产生数据的归宿地。
