A Business Smart Component (BSC) Workflow provides access to a remote instance of a BSC Workflow Implementation. A workflow defines an abstract interface to an object that implements a set of states and legal transitions between those states. This is a powerful metaphor that represents a variety of decision support structures. An implementation of a Workflow is the StateMachine class in The Theory Center's Axiom package. The Theory Center's SmartGenerator generates a workflow based on that StateMachine, directly from a State Diagram
