Enterprise Architecture for Integration

I’ve wanted to get my hands on a copy of this book for a numbers of years and it didn’t disappoint me. Written by one of the doges of EA this 500 page tomb will have no doubt attracted more than its fair share of detractors.

In this world of short attention spans almost anybody who pays more than a passing nod to Zachman seems to be immediately labeled as either too academic or simply too methodologically heavy.  If you’re of this ilk then this is not the book for you. However, if completeness and rigor are the heart of your philosophy then this is a book for you.

The book opens with the obligatory evolution of EA chapter, trotting out the usual stuff you’d expect. And then it shifts focus to Finkelstein’s real passion in a chapter entitled Using Enterprise Architecture for Enterprise Integration. It is in his treatment of data and meta data in particular that this book makes its contribution. Data as the fine grain of integration is its underlying theme. Perhaps not surprising for Finkelstein.

Part one literally covers off the business end of EA with chapters on Strategy Maps and Balanced Score Cards and business planning.

Part two discusses methodologies, SDLC, EA and Governance are all covered. It also takes a look at DoDAF, Modelling, Alignment and Business Normalization and even screen design. But its real contribution for me is the “Business Driven Data Mapping for Integrated Data” chapter.

Part three is a reasonable, but perhaps half hearted technology overview, but by now the book has made its point. But, there is an interesting after thought about the semantics of messaging that is worth your consideration.

On the casual to rigorous scale this book is definitely off towards the rigorous end and this will not make it popular with those who have yet to suffer sufficient pain to realise that there is no substitute for rigor.

A book for the technicians, highly recommended.
