- 3. UseCase Diagram with Extend & Include Relationship
- 4. Extends Relationship: The extend-relationship connects an extension use case to a base use case. You define where in the base to insert the extension by referring to extension points in the base use case. The extension is conditional, which means its execution is dependent on what has happened while executing the base use case. The base use case does not control the conditions for the execution of the extension – the conditions are described within the extend-relationship
