Activity Diagrams

Activity diagrams are essentially flowcharts showing flow from activity to activity. Activity diagrams model sequntial steps in a computational process. Activity diagrams may stand alone to visualize the dynamics of a society of objects, or they may be used to model the flow control of an operation, or use case.

Figure 1 Shows an example activity diagram detailing a customer ordering a product. There are several activities denoted by the oval shapes. This activity diagram also tracks the transition of two objects through the activity -- Order and Bill.
