The output function ω represents the mapping of ordered pairs.

What is a state diagram. A state diagram also known as 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. Steps to draw a state diagram identify the initial state and the final terminating states. State diagrams are used to give an abstract description of the behavior of a system.

This behavior is represented and analyzed in a series of events that occur in one or more possible states. 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.

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. Identify the possible states in which the object can exist boundary values corresponding to different attributes guide us in identifying different states. Sometimes its also known as a harel state chart or a state machine diagram.

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. Using our collaborative uml diagram software build your own state machine diagram with a free lucidchart account today. 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 the unit of code representing that entity.

A state diagram shows the behavior of classes in response to external stimuli. Label the events which trigger these.
