State Machine Diagram Tutorial

State machine diagrams are used to capture the behavior of a software system. As an example the following state machine diagram shows the states that a door goes through during its lifetime.

Using our collaborative uml diagram software build your own state machine diagram with a free lucidchart account today.

State machine diagram tutorial. 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 machine diagrams commonly known as state diagrams are a useful way of. Activity diagram explained in the next chapter is a special kind of a statechart diagram.

State machine diagrams are also called as state chart diagrams. Tutorial 5 steps to draw a state machine diagram page 2 of 11 3. Now let us discuss about these two state machines one by one.

Uml state machine diagrams can be used to model the behavior of a class a subsystem a package or even an entire system. Use state diagrams the design frameworks for state machines to model the control algorithms you need with discrete logical states. The block diagram of mealy state machine is shown in the following figure.

A statechart diagram describes a state machine. A finite state machine is said to be mealy state machine if outputs depend on both present inputs present states. What is a state machine diagram.

The figure below is an example of a state diagram. This page provides a tutorial for drawing state diagrams in the unified modeling language uml. 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.

A state machine diagram models the behaviour of a single object specifying the sequence of events that an object goes through during its lifetime in response to events. State diagrams make it easy to develop and understand the functionality of an application that uses a state machine. Keep reading to learn the basic steps for building these diagrams in lucidcharta free user friendly diagramming platform.

A state machine diagram or start diagram also called state chart of state transition diagram is a behavior which specifies the sequence of states an entity or object visits during its lifetime in response to events together with its responses to those events. The new diagram appears with an initial state a solid black circle by default. Enter bank account as diagram name and click ok to create the diagram.
