Using Enterprise Integration Patterns (EIP) — design patterns for the integration of enterprise applications — can help solve several recurring problems that haunt IT staffs, including filtering of special parts of messages, splitting of messages in several parts, and collecting messages according to determined aspects and sending them in a bundle.

This book lays out the strategies, approaches, and planning required to efficiently use EIP. It then goes one step further, presenting the twelve most important patterns for the integration of heterogeneous services, applications, and systems with SAP NetWeaver PI. Based on specific, real-life problems, the authors identify the appropriate Enterprise Integration pattern and then show, in detail, how to implement it for SAP NetWeaver PI. And that's just for starters... Critical software components and examples used in the book are available for download on our Website!
