Unified model for authoring the flow-based and constraint-based workflow is executed

摘要

Designing and executing a workflow having flow-based and constraint-based regions A user selects one or more activities to be part of a constraint-based region. Each constraint-based region has a constraint associated therewith. The workflow is executed by executing the flow-based region and the constraint-based region. The flow-based region executes sequentially. The constraint is evaluated, and the constraint-based region executes responsive to the evaluated constraint.
