A Join Notations is a graphical notation used in a UML Activity Diagram to represent a join action that waits for multiple concurrent execution flows to finish.

A Join Notation is drawn as a short solid line with multiple incoming control flows on one side and one outgoing control flows on the other side. For example, the join action performed before the "Close Order" action to wait for both "Ship Order" action and "Send Invoice" action to finish can be drawn as a Join Notation in a UML activity diagram as shown below:
