建立大型的计算机化的企业信息系统,应该注重( )的数据规划和对不同用户领域的关系进行局部设计。

A.重点突出

B.横向发展

C.逐步求精

D.自顶向下

答案

参考答案:D

解析: 建立大型的计算机化的企业信息系统,应该注重自顶向下的数据规划和对不同用户领域的关系进行局部设计。 相关知识点: 自顶而下的数据规划和对不同用户领域的关系进行局部设计,两者必须结合,即局部设计是在自顶而下系统规划所建立的框架内进行,而对框架的每一部分,则采用逐步求精的设计方法来改善。 自顶而下的信息系统资源的规划和详细的数据库设计是建立计算机化的信息系统整套方法的两个重要组成部分,这两个部分应该互相兼容并且可以互相补充地加以运用。 自顶而下规划的主要目的是达到信息的一致性,如应保证在数据字段的定义和结构,记录和结构,更新的时间和更新的规划等方面的一致。
