This is a useful book that I have bought multiple copies of over the years and given to users and technical teams. The Zachman framework is an ideal way to represent views of systems that are useful for the various stakeholders, from business leaders to the technical staff. The book explains the various views in the framework completely and in plain English, useful for talking outside the IS shop and selling concepts. The value of this book is in how solidly it reinforces the critical nature of data and importance of good data management, even beyond the warehousing level.
