Activity Diagram - Fork Notation

This section describes the Fork Notation used in a UML Activity Diagram. A Fork Notation represents a fork action that splits a single execution flow into multiple concurrent execution flows.

A Fork Notations is a graphical notation used in a UML Activity Diagram to represent a fork action that splits a single execution flow into multiple concurrent execution flows.

A Fork Notation is drawn as a short solid line with one incoming control flow on one side and multiple outgoing control flows on the other side. For example, the fork action performed after the "Receive Order" action to start "Ship Order" action and "Send Invoice" action concurrently can be drawn as a Fork Notation in a UML activity diagram as shown below:
