Enterprise.Integration.Patterns

This book does not attempt to make a business case for enterprise application integration; the focus is on how to make it work. Readers of this book will learn how to integrate enterprise applications by understanding: • The advantages and limitations of messaging as compared to other integration techniques • How to determine the message channels your applications will need, how to control whether multiple consumers can receive the same message, and how to handle invalid messages • When to send a message, what it should contain, and how to use special message properties • How to route a message to its ultimate destination even when the sender does not know where that is • How to convert messages when the sender and receiver do not agree on a common format • How to design the code that connects an application to the messaging system • How to manage and monitor a messaging system once it’s in use as part of the enterprise Even readers who are familiar with these practices will benefit from having them documented and being able to use them to facilitate communication with their colleagues.
