Statechart Diagram
Statechart diagram describes the sequence of steps the object goes through in response to external events. It binds transitions with message sends and conditions on object. A state is a condition satisfied by the attributes of an object. A transition represents a change of state triggered by events, conditions, or time.
A state is depicted by a rounded rectangle. A transition is depicted by an open arrow connecting 2 states. A small solid black circle indicates the initial state. A circle surrounding a solid black circle indicates a final state.
Below are the statechart diagram for our distance learning system:
