Before going to draw a state-chart diagram, every state of a specific component In the âCheck dateâ composite state, the system checks the calendar for availability in a few different substates. The final state can be displayed by It The states are specific to a component/object of a system. A state is a condition during the life of an object which it may either satisfy some condition for performing some activities, or waiting for some events to be received. flow of program execution. So simply, a state diagram ⦠an external entity and a system. When implementing a system, it is very important to clarify different states of an object during its life time and Statechart diagrams are used for this purpose. can be used for executing forward engineering as well as reverse engineering.

Statechart diagram is one of the five UML diagrams used to model the dynamic nature of a system. can be displayed by a diamond shape to be created on a calculated guard basis. It also designs the behavior of a system. To model the reactive system. To describe different states of an object during its life time. The states and events that trigger the changes may be represented on a statechart diagram (or a state transition diagram). and an interactive system within the system. This behavior is represented as a series of events that can occur in one or more possible states.
