### 5.2.2测试与作业 ###

> 1判断(2分)判断题：所有的数据流图都可以看作变换型数据流图。  
> A.2.00/2.00B.  
> 正确答案:对

> 2单选(2分)对于变换设计的基本步骤，正确的顺序是\_\_\_\_\_\_  
> ① 确定输入、变换、输出三部分之间的边界  
> ② 系统模块结构图顶层和第一层的设计  
> ③ 复审并精化系统需求模型  
> ④ 自顶向下，逐步求精  
> A.①②③④B.②①③④C.③①②④D.①③②④  
> 正确答案:C

> 3单选(2分)下列说法错误的是\_\_\_\_\_\_  
> A.变换型DFD是由输入、变换和输出三部分组成  
> B.变换设计中，有几个物理输入就设计几个输入模块 //是有几个逻辑输入就设计几个输入模块  
> C.事务型DFD一般只接受一个输入数据  
> D.通常来说，变换型数据流图更加常见，而事务型数据流图往往作为局部出现  
> 正确答案:B

> 4单选(2分)关于事务设计，下列说法正确的是\_\_\_\_\_\_  
> A.事务设计的第一步是确定事务处理中心 //第一步是 设计准备，复审和精化系统模型  
> B.在第一级分解中，需要为每一条活动路径设计一个事务处理模块  
> C.在第一级分解中，需要分别设计输入输出模块  
> D.在第二级分解中，对各条路径的细化类似于变换设计的细化过程  
> 正确答案:B
