第1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。

第7题：

（ ）analysis emphasizes the drawing of pictorial system models to document and validate both existing and/or proposed systems.Ultimately,the system models become the（ ）for designing and constructing an improved system.（ ）is such a technique.The emphasis in this technique is process-centered.Systems analysts draw a series of process models called（ ）、（请作答此空）is another such technique that integrates data and process concerns into constructs called objects.

A.Structured analysis
B.Information Engineering
C.Discovery Prototyping
D.Object-Oriented analysis

答案：D
解析：
模型驱动的分析方法强调通过绘制图形化的系统模型来说明和验证已有的或待开发的系统。这些系统模型最终会成为设计和构建改进后的系统的蓝图。结构化分析就是这样一种方法，它是以过程为中心的。在结构化分析方法中，系统分析员所绘制的一系列过程模型被称为DFD。面向对象分析是另外一种模型驱动的分析方法，它将数据和过程统一到了一个被称为"对象"的结构中。
