BEA Systems, Inc. recently announced the launch of new family of products for
service infrastructure, named AquaLogic. AquaLogic Service Bus (ALSB) is
BEA's implementation of the Enterprise Service Bus combined with Web services
management capabilities. This article is a high-level introduction to ESB and
In their Harvard Business Review article, Giovanni Gavetti and Jan W. Rivkin
explain the power of reasoning by analogy. They explain how successful
executives have tapped the power of analogy to build businesses by comparison
to other successes in business history. Analogy can also be used to
understand new concepts and to predict the future of the concept. In this
article I use the analogy of Universal Serial Bus (USB) to understand
Enterprise Service Bus.

As a software architect and developer, I've used a number of IDEs for my J2EE

Service-oriented architecture (SOA) has become today's technology buzz and

A business process in the real world typically is never done end-to-end by a
single employee. It usually involves multiple employees/back end systems
handing over work, similar to a 4x100 track relay where batons are passed

great framework to build these business processes for deployment on the
WebLogic Platform. Applications and Business Processes - What's the
