Timing Diagram

About

A Timing Diagram models the state of objects over time, focusing on time-based changes in interactions. It is useful for real-time systems, embedded systems, and protocol modeling.

Key Elements

1. Lifelines (Objects or Entities)

   • Represented as horizontal lines, showing how an entity behaves over time.

2. States

   • Represented as labels along the timeline (e.g., "Idle", "Processing", "Completed").

3. Time Axis

   • Represented as a horizontal timeline tracking event occurrences.

4. State Changes

   • Vertical transitions show state changes at specific time intervals.

5. Messages

   • Represented as arrows between lifelines.
