What Is A State Diagram

Specifically a state diagram describes the behavior of a single object in response to a series of events in a system. State machine diagram is a behavior diagram which shows discrete behavior of a part of designed system through finite state transitions.

What Is State Machine Diagram

A state diagram is the graphical representation of a state machine and one of the 14 uml diagram types for software and systems.

What is a state diagram. State machine diagram is a uml diagram used to model the dynamic nature of a system. A state diagram also called a state machine diagram or statechart diagram is an illustration of the states an object can attain as well as the transitions between those states in the unified modeling language uml. A state diagram also called a state machine diagram or statechart diagram is an illustration of the states an object can attain as well as the transitions between those states in the unified modeling language uml.

State machine diagrams can also be used to express the usage protocol of part of a system. Activity diagram explained in the next chapter is a special kind of a statechart diagram. Two kinds of state machines defined in uml 24 are.

State diagrams show a behavioural model consisting of states state transitions and actions. State diagrams require that the system described is composed of a finite number of states. Uml state diagrams are based on the concept of state diagrams by david harel.

A statechart diagram describes a state machine. Sometimes its also known as a harel state chart or a state machine diagram. Uml statechart diagrams.

State machine can be defined as a machine which defines different states of an object and these states are controlled by external or internal events. This behavior is represented and analyzed in a series of events that occur in one or more possible states. Definition what does state diagram mean.

A state diagram is a type of diagram used in computer science and related fields to describe the behavior of systems. This uml diagram models the dynamic flow of control from state to state of a particular object within 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.

A state diagram is a diagram used in computer science to describe the behavior of a system considering all the possible states of an object when an event occurs. State machine diagrams can also show how an entity responds to various events by changing from one state to another. Sometimes this is indeed the case while at other times this is a reasonable abstraction.

In this context a state defines a stage in the evolution or behavior of an object which is a specific entity in a program or. In this context a state defines a stage in the evolution or behavior of an object which is a specific entity in a program or.
