Summary: too superficial to be useful
Review: This book aims at a good target: explaining EAI to managers. To accomplish this task, the author needed full descriptions of the concepts and meaty examples to illustrate them. This book has neither.For example, the author states several times that SAP needs a richer collection of APIs in order to connect to other application. Nowhere does he describe what is missing: what functionality is hard to access in SAP that should be easy? Save your money.

Summary: EAI for Everyone
Review: This book does a great job as attacking this topic without the fluff. I'm not that technical but I was able to understand most of the concepts outlined in the book. It would have been nice to see more information on XML, but I was still very pleased with this book.

Summary: A Classic
Review: This book provides a great overview of some very complex technology. I think the author does a great job in putting this technology in terms that one can understand and apply in his or her own enterprise. I use this book daily. This book covers the entire scope of EAI, allowing you to break down your own enterprise into components, and than selecting the correct technology to solve your problem. This is one of those book that you have to have on your shelf, along with other classics.

Summary: Great Overview of Application Integration for Beginners
Review: This book took me from 0 to 60 in the new world of application integration. This is a teaching book, you'll move from very basic concepts to more advanced descriptions of application integration technology. What I liked most about it was that the author does not assume that you're a technology guru, and explains things as you go along. In other words, you don't need to read 6 other books to understand this one. This is an IT classic that you need for your shelves, I got mine.

Summary: Tells you a little bit of everything involved in EAI.
Review: This book touches a little bit of everything about enterprise application integration e.g. database gateways, EDI, Message Queues, data level integration, application level integration etc. It uses SAP and Peoplesoft's HR system as examples. However, everything it touches is only on the surface. I think this book may be useful for experienced systems persons who are starting to work on EAI or B2B as a quick introduction and resource guide.
