This book illustrates numerous EAI patterns (in the same line as the "Gang of Four") and demonstrates how multiple patterns seamlessly coexist and co-ordinate in EAI architecture. The importance of specific patterns based on application architecture and the schematics is described lucidly. Explains how to transform the theory in practice and how to implement an EAI. Talks about many EAI products (Biztalk, TIBCO, MQ Series etc.) along with the process to implement the patterns with them as integrator. A book surely closer to us; who wants to see it (Sample Codes are helpful) to believe it. Surprised to see only one review on such an exciting book. A Must have for the architects who just does not depend on vocabulary to earn a living.
