Middleware (distributed applications) - Message broker

1 Part of an enterprise messaging system, message broker software

may queue, duplicate, translate and deliver messages to disparate systems or components in a

messaging system.


Message broker

1 'Message broker' is an intermediary program which translates the

language of a system from one to another by way of a

telecommunications medium.


Message broker - Pattern

1 A message broker is an architectural pattern for message validation,

message transformation and message routing.


Message broker - Broker functionality

1 Many messaging patterns (like publish–subscribe) can work without a message broker. One pattern that

requires a message broker is workload queues, that is message

queues that are handled by multiple receivers. Such queues must be

managed, transacted, and usually stored reliably, at a single point.

IBM WebSphere Message Broker

1 'WebSphere Message Broker' (WMB) is IBM's integration Message broker|broker from the

WebSphere product family that allows business information to flow between disparate

applications across multiple hardware and software platforms. Rules can be applied to the

data flowing through the message broker to route and transform the information. The

product is an Enterprise Service Bus providing connectivity between applications and services

in a Service Oriented Architecture.


IBM WebSphere Message Broker - History

1 After 2.1 the version numbers became more synchronized with the rest of the

WebSphere family and jumped to version 5.0. The name changed to 'WebSphere Business Integration Message Broker'

(WBIMB). In this version the development environment was redesigned using

Eclipse (software)|Eclipse and support for Web services was integrated into the

product.



1 WebSphere Message Broker version 7.0 was announced in October 2009,[ http://www-01.ibm.com/common/ssi/cgi-bin/ssialias?

IBM WebSphere Message Broker - Overview

1 The WebSphere Message Broker runtime reduces cost and complexity of IT systems by

unifying the method a company uses to implement interfaces between disparate

systems. WMB runtime forms the Enterprise Service Bus of a Service Oriented Architecture

by efficiently increasing the flexibility of connecting unlike systems into a unified,

homogeneous architecture. The key feature of the WMB product is the ability to abstract the business logic away from transport or protocol

specifics.



1 At this point, the broker is able to continually process messages

according to the logic described by the message

flow.[http://publib.boulder.ibm.com/infocenter/wmbhelp/v7r0m0/topic/

variety of data formats are supported, and may be modeled

using standard XML Schema (W3C)|XML Schema and DFDL schema

capabilities that enable analysis of events to perform validation,

enrichment, transformation and intelligent routing of messages based

on a set of business rules.
