What Is A State Diagram

Uml state diagrams are based on the concept of state diagrams by david harel. 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.

State Diagrams And State Tables

Uml statechart diagrams.

What is a state diagram. State machine diagram is a behavior diagram which shows discrete behavior of a part of designed system through finite state transitions. State diagrams show a behavioural model consisting of states state transitions and actions. Sometimes its also known as a harel state chart or a state machine diagram.

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. A state diagram is a type of diagram used in computer science and related fields to describe the behavior of systems.

State machine diagram is a uml diagram used to model the dynamic nature of a system. State diagrams require that the system described is composed of a finite number of states. Sometimes this is indeed the case while at other times this is a reasonable abstraction.

This behavior is represented and analyzed in a series of events that occur in one or more possible states. State machine diagrams can also show how an entity responds to various events by changing from one state to another. 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.

State machine diagrams can also be used to express the usage protocol of part of a system. Specifically a state diagram describes the behavior of a single object in response to a series of events in a system. Activity diagram explained in the next chapter is a special kind of a statechart diagram.

A statechart diagram describes a state machine. Two kinds of state machines defined in uml 24 are. Definition what does state diagram mean.

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. This uml diagram models the dynamic flow of control from state to state of a particular object within a system. A state diagram is the graphical representation of a state machine and one of the 14 uml diagram types for software and systems.

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. Uml state machine diagrams or sometimes referred to as state diagram state machine or state chart show the different states of an entity.
