BPEL koncepci | BPEL forrskd is the top level element, channel use to interact with client (and services integrated in process): reference to an XML message receive or sent to the s.Process flow: sequence of activities defining the process logic.Initiate a new instance of the process when a process request is receivedCreate and assign greeting to output message.Send synchronous reply to client passing output variable as response

World Wide Web Consortium (W3C) refers to SOA as 'A set of components which can be invoked, and whose interface descriptions can be published and discoveredLooking around we see the term or acronym SOA becoming much more widely used, and there isnt a lot of precision in the way that it's used. Usually it's a very technical perspective in which the architecture is considered a technical implementation. Which is odd, because the term architecture is more generally used to describe a style or set of practices. SOA is an architectural style whose goal is to achieve loose coupling among interacting software agents. A service is a unit of work done by a service provider to achieve desired end results for a service consumer. Both provider and consumer are roles played by software components.

Let's look at an example of SOA which is likely to be found in your living room. Take a CD for instance. If you want to play it, you put your CD into a CD player and the player plays it for you. The CD player offers a CD playing service. Which is nice because you can replace one CD player with another. You can play the same CD on a portable player or on your expensive stereo. They both offer the same CD playing service, but the quality of service is different.

There is a constant pressure for businesses to interconnect their applications. This is what is driving the adoption of web services and SOA as an enterprise blue print for reducing the cost and complexity of integration initiatives. Making web services work is a two step process: first you publish and then you orchestrate. Publish means taking a part of a existing system and exposing it as a service. Orchestrate means composing multiple discrete services into an end-to-end process flow. BPEL is the industry standard for orchestration.
