UML Activity Diagram

essentially a flowchart shows flow of control from activity to

activity.

Activity Diagram

UML Collaboration Diagram

an interaction diagram emphasizes the structural organization of the

objects that send and receive messages. Shows:

a set of objects links among those objects messages sent and received by those objects.
