Overview

About the uml sequence diagram template

A sequence diagram shows how parts of a system talk over time. Lifelines represent the participants and arrows show the messages between them, so a request-and-response flow is easy to reason about.

This template is the built-in Sequence (auth) diagram in the Atlas Diagram Studio gallery. It opens with client, server, and database lifelines and a login exchange, including dashed return messages.

Because it is a live Diagram Studio document, you edit the participants and messages directly, so the diagram models your interaction.

FAQ

Questions, answered.

What is a UML sequence diagram?
A sequence diagram shows the messages exchanged between participants over time, using lifelines for the participants and arrows for requests and responses, so an interaction is clear.
Why are some arrows dashed?
By convention, solid arrows are calls or requests and dashed arrows are returns or responses. The template follows this so the login exchange reads correctly.
Can I model a different interaction?
Yes. The template is a live diagram, so you can rename participants and edit the messages to model any request-and-response flow.
