Sequence diagrams are a crucial tool in software development, showing how objects interact in a particular scenario of a system.

What are Sequence Diagrams?

A sequence diagram shows the sequence of messages between objects over time. It visualizes how different components of a system communicate.

Key Elements

• Actors: Users or systems interacting with the system
• Objects: The components involved in the interaction
• Messages: Communications between objects
• Activations: When a method is being executed

Benefits for Developers

Sequence diagrams help developers understand existing systems, plan new features, and communicate with stakeholders about system behavior.
