[Enterprise Architecture Framework ]企业架构框架

准备写一个what, why, who, how系列的，希望能够坚持深入下去。
其实目的（Why）应该放在前面的，但先迫不及待的下笔写了What，现在看看，也没什么不妥。

在写what的过程中，提到了两个EA框架，本文就此做个小调查的笔记，参考资料主要来自：

EA框架的发展历史
EA框架的历史也就是EA的历史，Zachman创建了他的Zachman框架，也是EA的开始。第二个框架TAFIM是一个开源的EA框架。
 * Zachman Framework
    1987

 * "Technical Architecture Framework for Information Management" (TAFIM)
    1991

Overview
 * 关注点：
    * Views : provide the mechanisms for communicating information about the relationships that are important in the architecture
    * Methods : provide the discipline to gather and organize the data and construct the views in a way that helps insure integrity, accuracy and completeness
    * Training/Experience : support the application of method and use of tools
 * 产生原因：使面对复杂问题时可以理清关注点，明确对输出结果的要求
 * 应用领域：IT和信息系统管理

EA Frameworks的话题
 * 是IT建设规范：Frameworks contain models and standards that will be used to develop IT architecture descriptions.
 * 架构域：Business/Data/Applicatoin/Technical，其中数据和应用域属于信息系统
 * EA分层：同上，自上而下，planner"s view, owner"s view, designer"s view and developer"s view
 * 视图模型
