UML和模式应用读书笔记/要点概记

1. OOA/D初步

a. OOA/D的一个重要的问题，就是能够熟练的赋予各个软件组件相应的职责。

A critical, fundamental ability in OOA/D is to skillfully assign responsibilities to software component.

b. 分析和设计的区别：分析强调对要解决的问题和客户需求进行调查，而不是给出一个解决方案；设计强调的是针对需求提供一个概念性的解决方案，但是不涉及到实现细节。

Analysis emphasizes an investigation of the problem and requirements, rather than a solution; Design emphasizes a conceptual solution that fulfills the requirements, rather than its implementation.

c. 什么是面向对象的分析与设计？

面向对象分析，就是找出问题与中的对象或者概念；面向对象设计，就是定义这些对象是其能够满足需求。

During object-oriented analysis, there is an emphasis on finding and describing the objects--or concepts--in the problem domain. During object-oriented design, there is an emphasis on defining software objects and how they collaborate to fulfill the requirements.
