Activity Model Definitions Workflow = sequence of processing steps that completely handles one business transaction. Swimlane = component responsible for performing the activities. Activity Diagram = model which describes the various user or system activities, component responsible for each activity, and the sequence of events. Synchronization (Fork/Split) = point in the model where the conclusion of one activity results in the transition to two or more concurrent activities. Synchronization (Join) = point in the model where future activity is suspending until the conclusion of two or more concurrent activities.
