This book will assist the senior level technology professional in turning EAI strategy into reality. The books currently on the market provide an "academic" overview of EAI. They describe the relevant technologies and explain their importance but they do not provide the necessary tools to turn textbook material into an EAI success story. This book will provide a solution focus to EAI. It will begin by stepping readers through an overview of EAI, leading them through the analysis of patterns of integration and then cover the tools and technologies that solve the EAI problem. Topics include:
