What is state machine diagram (UML)?

A state diagram is a type of diagram used in UML to describe the behavior of systems which is based on the concept of state diagrams by David Harel. State diagrams depict the permitted states and transitions as well as the events that effect these transitions. It helps to visualize the entire lifecycle of objects and thus help to provide a better understanding of state-based systems.

A state machine diagram is used to model the dynamic behavior of individual class objects, use cases, and entire systems. In other words, when a state machine created where the object it is attached to, that object becomes the owner of the state machine, for example, the object to be attached by the state machine could be a class, use case or even the entire system.

A state machine diagram is a behavior that specifies the sequences of states an object goes through during its lifetime in response to events. A state machine are used to specify the behavior of objects that must respond to asynchronous stimulus or whose current behavior depends on their past. A state machines are used to model the behavior of objects, use cases, or even entire systems, especially reactive systems, which must respond to signals from actors outside the system.
