博客介绍了一本优秀书籍，虽前两部分内容一般，但第三部分（第8 - 16章）很出色。着重阐述了组件 - 复合（Components - Composite）和组成部分（Consituent）的区别，以班级为例说明组件是异构的，而组成部分是相似的。
Wonderful book,with no other words to evaluated it.
Materials in first and second parts of this book is not so good ,but part 3,from Chapter8 to Chapter 16 is excellent than other books I have seen.Some issues will be writen down in details and share with you.
1.difference between Components-Composite and Consituent.
There is only vital difference between them that can distinguish them clearly.That is
Components are isomerous,but Consituent are not.
Let's take a class as an example.
Components-Composite:A classic class is made of some students,management systems,ect.
Consituent:Each students is a member of a class.
So ,the difference is obvious.Students and management totally “isomerous”,they have isomerous studcture,characters,presentation and so on.By contrast, sutudents of a class may be male or female,in different age,but they are so similar to each other.Generally,we can design only one class for it.
