The Sequence diagram shows the message flow from one object to another object. The Activity diagram shows the message flow from one activity to another.

What is the purpose of statechart diagram?

Statechart diagram describes the flow of control from one state to another state. States are defined as a condition in which an object exists and it changes when some event is triggered. The most important purpose of Statechart diagram is to model lifetime of an object from creation to termination.

What is the difference between state diagram and activity diagram?

UML State machine diagram and activity diagram are both behavioral diagrams but have different emphases. Activity diagram is flow of functions without trigger (event) mechanism, state machine is consist of triggered states.

What are the differences between activity diagram and sequence diagram?

What is the difference between activity diagram and flowchart?

What are the main differences between sequence diagrams and class diagrams?

What is the difference between class diagram and use case diagram?

What is the difference between sequence and state chart diagram?
