Cas d’Utilisation
Relations
Association – The participation of an actor in a use case; that is, instances of the actor and instances of the use case communicate with each other. This is the only relationship between actors and use cases.
Extend – An extend relationship from use case A to use case B indicates that an instance of use case B may be augmented (subject to specific conditions specified in the extension) by the behavior specified by A. The behavior is inserted at the location defined by the extension point in B, which is referenced by the extend relationship.
Generalization – A generalization from use case C to use case D indicates that C is a specialization of D.
Include – An include relationship from use case E to use case F indicates that an instance of the use case E will also contain the behavior as specified by F. The behavior is included at the location which defined in E.
