内容
• 企业架构模型
– Zachman模型 – 企业信息架构发展与概念
EA Origin – John Zachman
• Mr. Zachman focused on architecture since 1970. His 1st article and the original framework was published in 1987 (“A Framework for Information Systems Architecture,” IBM Systems Journal, vol. 26(3), 1987. /journal/sj/2 63/ibmsj2603E.pdf ). In 1992 John Zachman and John Sowa wrote another article (“Extending and Formalizing the Framework for Information Systems Architecture." J.F. Sowa and J. A. Zachman. IBM Systems Journal, vol. 31, no. 3, 1992. /journal/sj/3 13/sowa.pdf) expanded the framework to its current 36 cell framework (“Enterprise Architecture – A Framework”).

Rule 1:
Columns have no order Rule 2:
Each column has a simple, basic model
