What Is A State Diagram

Sometimes this is indeed the case while at other times this is a reasonable abstraction. Using our collaborative uml diagram software build your own state machine diagram with a free lucidchart account today.

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.

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. Emphasis is placed on the state changes upon some internal or external events. These states of objects are important to analyze and implement them accurately.

State diagrams require that the system described is composed of a finite number of states. A state diagram is used to represent the condition of the system or part of the system at finite instances of time. The state diagram from figure 2 is an example of an extended state machine in which the complete condition of the system called the extended state is the combination of a qualitative aspectthe stateand the quantitative aspectsthe extended state variables such as the down counter keycount.

State machine diagrams can also show how an entity responds to various events by changing from one state to another. This uml diagram models the dynamic flow of control from state to state of a particular object within a system. Definition what does state diagram mean.

State machine diagram is a uml diagram used to model the dynamic nature of a system. In most oo techniques state diagrams are drawn for a single class to show the lifetime behavior of a single object. These terms are often used interchangeably.

Uml state machine diagrams or sometimes referred to as state diagram state machine or state chart show the different states of an entity. Statechart diagram is used to describe the states of different objects in its life cycle. 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.

State machine diagram tutorial. Its a behavioral diagram and it represents the behavior using finite state transitions. 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.

They describe all of the possible states that a particular object. State diagrams are also referred to as state machines and state chart diagrams. A state diagram also called state machine diagram statchart and start transition diagram is a type of diagram behavior diagram in uml.

Statechart diagrams are very important for describing the states. This behavior is represented and analyzed in a series of events that occur in one or more possible states. Sometimes its also known as a harel state chart or a state machine diagram.

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