How do you draw a state chart 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 is state in state chart 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 activity and state chart 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.
Do activities state diagram?
An activity diagram is a special case of a state chart diagram in which all or most of the states are activity states and all or most of the transitions are triggered by completion of activities in the source state (An activity is an ongoing non-atomic execution within a state machine).
How do you explain a state machine diagram?
State diagrams mainly depict states and transitions. States are represented with rectangles with rounded corners that are labeled with the name of the state. Transitions are marked with arrows that flow from one state to another, showing how the states change.
What should be the name of a state chart diagram?
An understandable and unique name must be referred to as a state transition that defines the nature of a system. In the state-chart diagram, only the most necessary objects are executed. A legitimate name must be assigned to the transitions and the events. It executes the object-oriented as well as real-world systems.
How is a statechart diagram used in UML?
Statechart diagram is one of the five UML diagrams used to model the dynamic nature of a system. They define different states of an object during its lifetime and these states are changed by events. Statechart diagrams are useful to model the reactive systems.
How are reactive systems defined in a statechart diagram?
Reactive systems can be defined as a system that responds to external or internal events. 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.
What do States represent in SmartDraw state diagram?
States States represent situations during the life of an object. You can easily illustrate a state in SmartDraw by using a rectangle with rounded corners. Transition A solid arrow represents the path between different states of an object. Label the transition with the event that triggered it and the action that results from it.
