System and method for dynamic sequencing of a requirements-based workflow

摘要

A system, and a corresponding method, allow for dynamic sequencing of a requirements-based workflow. The system includes a registry that stores information related to services available to complete a received job request. The system also includes a workflow controller capable of dynamically generating a workflow based on the received job request. The workflow controller includes a rules database containing rules that specify requirements for constructing the workflow based on a nature of the job request. The workflow includes one or more nodes, and the workflow controller dynamically generates the workflow by comparing the requirements of the rules to outputs of prior nodes to generate subsequent nodes. Finally, selected services execute the nodes.
