Behavioral Modeling
Design and model system interaction with UML sequence diagram and communication diagram. Design and model dynamic behavior with activity diagram. Show critical state change with state machine diagram.
Sequence diagram
Sequence diagram sample with keyboard control panel
Sequence diagram shows interaction between users, systems and sub-systems, and emphasize the ordering of time of messages. You can draw sequence diagram solely by mouse or with keyboard shortcuts.
Communication diagram
Communication diagram
Communication diagram shows similar information as sequence diagram, but communication diagram emphasizes the structural organization of the objects' send and receive messages. Communication diagram is designed for illustrating the dynamic view of the system. Visual Paradigm for UML supports group and un-group messages into single or multiple arrow head for easy layout of the communication diagrams.

Activity diagram
Activity diagram is a flowchart-based diagram showing flow of control from activity to activity. Activity diagram shows concurrency, branch, control flow and object flow. Swimlane is useful for partitioning the activity states. Activity diagram is commonly used for elaborating use case in use case diagram.
