RE: [service-orientated-architecture] Orchestration, Choreography , and Composition

[Teresa Jones]

As a musician, I would say that all words are incorrectly used in IT.... However, I would perhaps try to define: Composition - putting together 'services' to make a 'composite application' - i.e. one that may then be fairly fixed for some time. Choreography - the ability to sequence (loosely) services (which could be human or computer) to be a business process. Orchestration - probably the same as the above, but perhaps at a higher level?   Teresa From: Ashley at Metamaxim [mailto:[EMAIL PROTECTED] Sent: 19 July 2006 15:10 To: service-orientated-architecture@yahoogroups.com Subject: Re: [service-orientated-architecture] Orchestration, Choreography, and Composition Todd wrote:   > I thought I'd turn this into a group exercise and see how all of you > define it. (i.e., Orchestration, Choreography, and Composition)   Excellent. This should be fun!   In my view, Choreography defines a behavioural protocol to which multiple parties must (or should) adhere when engaged in a service based collaboration. I am sure that Steve R-T will give us the definitive definition of Choreography!   Like you, Todd, I am not clear whether there is any real difference between Orchestration and Composition. Perhaps Orchestration is the means by which Composition is achieved?   Rgds Ashley ********************************************************************* IMPORTANT NOTICE   The contents of this e-mail are privileged and confidential and intended for the addressee at the specified e-mail address only.
