service composition
|
A service composition is an aggregate of services collectively composed to automate a particular task or business process. To qualify as a composition, at least two participating services plus one composition initiator need to be present. Otherwise, the service interaction only represents a point-to-point exchange.
Service compositions can be classified into primitive and complex variations. In early service-oriented solutions, simple logic was generally implemented via point-to-point exchanges or primitive compositions. As the surrounding technology matured, complex compositions became more common.
Much of the service-orientation design paradigm revolves around preparing services for effective participation in numerous complex compositions. So much so that the Service Composability design principle exits, dedicated solely to ensuring that services are designed in support of repeatable composition.
