UML tool: Use case diagrams

Examples of UML use case diagrams with Modelio

UML use case diagrams belong to the family of behavioral diagrams, and enable you to model interactions between actors and system. The examples below show how to represent these interactions using use case diagrams.

Use case modeling is a very popular practice in UML. It helps formalize how an application is intended to be used, who the expected users are, and what kind of use each user will make of the application.

Modelio supports use case modeling with all its subtleties, such as include or extend links, and extension points.
