Patterns: Broker Interactions for Intra- and Inter-enterprise

Preface

The Patterns for e-business are a group of proven, reusable assets that can be

used to increase the speed of developing and deploying Web applications.

This IBM® Redbook concentrates on distributed application integration using the

Process-focused Application Integration::Broker application pattern for

intra-enterprise, and the Extended Enterprise::Exposed Broker application

pattern for inter-enterprise.

Part 1 guides you through the process of selecting an Application and Runtime

pattern. Next, the platform specific Product mappings are identified based upon

the selected Runtime pattern.

Part 2 presents guidelines on applying the Patterns approach to a sample

business scenario and on selecting application integration technologies.

Part 3 provides detailed design, development, and runtime guidelines for

intra-enterprise and inter-enterprise integration solutions. It teaches you by

example using IBM WebSphere Application Server V5.0 with WebServices

Gateway and WebSphere Business Integration Message Broker.
