Published

Author(s)

Conrad E. Bock

Abstract

This is the third in a series introducing the activity model in the Unified Modeling Language, version 2 (UML 2), and how it integrates with the action model. The previous article addressed the execution characteristics of actions in general, and additional functionality of actions that invoke behaviors. The first article gave an overview of activities and actions that is assumed here. The remainder of the series elaborates other specific elements. This article covers control nodes, which route control and data through the flow model. It also points out the differences in concurrency support between UML 2 and UML 1.x activities.
