as promised, a review of the book - Chapter by Chapter...
Chapter 1 - Understanding the Problem.
Reminds me of - Women are from Venus - Men are from Mars - the mismatch between business requirements and IT infrastructure/implementations.
The authors give a succinct overview of the problem space SOA is addressing.
Process silos - data and functional duplication are the common symptoms of this dichotomy.
They emphasise the role of architecture in addressing this and position SOA within this architectural world.
It details how SOA fits in with Enterprise Architecture, Reference Architecture, Solution Architecture & Project Architecture
Essentially a raison d,être for Service Oriented Architecture.
