   Average Customer Review: based on 52 reviews.
   Customer Review: Thomas Erl is SOA approach guru, this book should be read by everyone who wants to know about SOA and who are planning to implement. This applies to both IT and business managers. The best thing about this book are the case studies for each concept and the "plain english" analogy for each SOA concept. It is a must read.
