State Diagram. A state diagram is used to represent the condition of the system or part of the system at finite instances of time. A state diagram consists of states transitions events and activities.
They define different states of an object during its lifetime and these states are changed by events. Specifically a state diagram describes the behavior of a single object in response to a series of events in a system. Uml state machine diagrams or sometimes referred to as state diagram state machine or state chart show the different states of an entity.
It s a behavioral diagram and it represents the behavior using finite state transitions.
The state diagram is the pictorial representation of the behavior of sequential circuits. Many forms of state diagrams exist which differ slightly and have different semantics. It s a behavioral diagram and it represents the behavior using finite state transitions. A state diagram sometimes known as a state machine diagram is a type of behavioral diagram in the unified modeling language uml that shows transitions between various objects.
