Introducing BPEL


Business Process Execution Language (BPEL) is a standard that emerged in 2003 and was developed to enable orchestration of web services using an executable XML-based language. BPEL allows you to separate out the definition of your business process from the implementation of the services that it orchestrates. BPEL provides process flow operators such as conditional branching, parallel flow (split/join), and looping. The resulting BPEL process can itself be exposed as a web service, and therefore, be included in other business processes. You can read the BPEL standard at http://oasis-open.org/.

Long-running services

A business process can be short or long, taking minutes, days, or even months. For example, processing a mortgage application can take several weeks and can contain many steps. One of the strengths of BPEL is the way it is designed to handle such long running processes. It has built-in support for asynchronous processing so that when you call another service asynchronously...
