How do you explain a state machine diagram?
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.

How do you write a state diagram?
Steps to draw a state diagram –
- Identify the initial state and the final terminating states.
- Identify the possible states in which the object can exist (boundary values corresponding to different attributes guide us in identifying different states).
- Label the events which trigger these transitions.
What are state models?
A state model represents the process model for one type of record. A state represents the status of a record, for example Submitted, Assigned, Opened, and Closed. A CHANGE_STATE action is an activity performed by a user that moves a record to the next state.
What is the difference between state diagram and activity diagram?
Activity diagram is essentially a flowchart showing flow of control from activity to activity. A state chart diagram shows a state machine emphasizing the flow of control from state to state.
What is event in state diagram?
An event is the specification of a significant occurrence that has a location in time and space. In the context of state machines, an event is an occurrence of a stimulus that can trigger a state transition. A guard condition is evaluated after the trigger event for the transition occurs.
What is state model in OOMD?
A state model describes the sequences of operations that occur in response to external stimuli. As opposed to what the operations do, what they operate on, or how they are implemented.
Which is the best definition of a state machine diagram?
State machine diagram is a behavior diagram which shows discrete behavior of a part of designed system through finite state transitions. State machine diagrams can also be used to express the usage protocol of part of a system. Two kinds of state machines defined in UML 2.4 are.

What’s the difference between a state machine and a statechart?
Statechart diagram is used to capture the dynamic aspect of a system. State machine diagrams are used to represent the behavior of an application. An object goes through various states during its lifespan. The lifespan of an object remains until the program is terminated.
When is an object attached to a state machine?
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. What is a State Machine Diagram in UML?
