6.3.2 Test environment

In this section we describe the data flow and the products that enable it. As

mentioned in the previous sections, this scenario is basically the same as

Scenario A, except we have added the ESB. The environment and data flow is

depicted in Figure 6-5.

The enterprise service bus is the responsible for the systems integration and

communications. Services are executed to integrate the data warehouse and to

enable inter-application communications.

WebSphere Message Broker V6

In a service oriented architecture, WebSphere Message Broker can be the

connectivity layer. It optimizes information distribution between service

requesters and service providers. As examples, it can:

򐂰 Distribute any type of information across and between multiple diverse

systems and applications, providing delivery of the right information in the

right format at the right time.

򐂰 Reduce the number of point-to-point interconnections and simplify application

programming by removing integration logic from the applications themselves.

򐂰 Route information in real-time to any endpoint using a powerful

publish-and-subscribe matching engine.

򐂰 Validate and transform messages in-flight between any combination of

different message formats, including Web Services, other XML and non-XML

formats.

򐂰 Route messages based on (evaluated) business rules to match information

content and business processes

򐂰 Improve business agility by dynamically reconfiguring information distribution

patterns without reprogramming end-point applications.
