UML Activity Diagrams

UModel allows you to easily chart the dynamic flow of actions and illustrate decision points in your project with activity diagrams.

UML Activity Diagram

You’ll find the features of UModel to be advantageous and versatile as you draw UML activity diagrams to chart the dynamic behavior of your project. The UModel activity diagram toolbar includes fork nodes, join nodes, and activity partitions in both horizontal and vertical orientation so you can select the element you need in a single step.

If you want to formally indicate the semantics of activity initializations, the input pin, output pin, and value pin elements are similarly organized. When you place a pin, the Properties dialog offers pull-down menus to set all its characteristics.

The UML 2 specification greatly expanded the features and scope of activity diagrams beyond their earlier classification as a special case of state diagrams. Today, activity diagrams are flow charts for the 21st century, and UML modelers use activity diagrams to describe business rules, single use cases, a complex series of multiple use cases, processes with decision points and alternate flows, operations that take place in parallel or software flows and logic control structures.

Whether you are an analyst assigned to diagram business rules, or a developer who needs to document all the subtle features of an embedded system, UModel makes it easy to draw UML 2 activity diagrams that chart the dynamic behavior of your project and communicate your designs accurately and effectively.
