accessible in real-time in usable formats to every part of the business. Users can

access data faster and respond better to customer needs. Changes to the

business can be implemented faster, with fewer errors, and with no disruption to

the business applications.

With WebSphere Message Broker, customers can extract valuable data from

existing applications and other sources of data and use it elsewhere in their

business. They can even access and widely distribute data from applications for

which they no longer have the source code. Users do not need to make costly

changes to the applications to take a different view of the data they provide.

Users can be more confident that the information they share with their customers

is accurate, timely, and (through taking advantage of the reliability and

recoverability offered by WebSphere Message Broker) enhanced when used to

connect systems using the assured delivery features of WebSphere MQ.

4.5.2 Information distribution

In a service-oriented architecture (SOA), the enterprise service bus (ESB)

optimizes information distribution between service requesters and service

providers. Each enterprise can deploy its own unique ESB, reflecting how far it

has advanced toward becoming an on demand business.

As key members of the IBM WebSphere software portfolio, WebSphere MQ and

WebSphere Message Broker enabled you to begin deploying or widening the

deployment of your ESB. There is also WebSphere Enterprise Service Bus, for

predominantly Web services-based environments.

Some businesses may find that simple messaging-based connectivity between

well-matched applications provides the aspects of integration that they require to

implement an effective enterprise service bus. Other businesses may find that to

extend these capabilities into their wider deployed infrastructure, they realize

value of other parts of the WebSphere software portfolio. As key members of the

IBM WebSphere software portfolio, WebSphere MQ and WebSphere Message

Broke, and WebSphere Enterprise Service Bus, enable deployment of an ESB.

These programs help maximize the value of your IT investment by broadening

the range of environments this connectivity layer can reach, such as hardware

and operating system platforms and non-standards-based programming models

as well as J2EE and .NET.

For connecting these diverse programming models there needs to be proven

delivery of messages and data between the applications. The proven delivery

mechanisms of WebSphere MQ and WebSphere Application Server can extend

the standards-based enterprise service bus with reliable connectivity throughout
