Abstract

This is the fourth in a series introducing the activity model in the Unified Modeling Language, version 2 (UML 2), and how it integrates with the action model [1]. The first article gives an overview of activities and actions [2], while the second two cover actions generally and control nodes [3][4]. The remainder of the series elaborates other specific elements. This article covers object nodes, which hold data temporarily as it waits to move through an activity.
