3. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 3 a) Actors b) Use Cases a) Relationships Diagram child father base addition extension base << include >> << extend >>
4. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 4 § Show that behavior of the included use case (addition) is inserted into the behavior of the including (base) use case. § A dashed line with an open arrowhead directed from the including use case (base) to the included (addition) use case. The arrow is labeled with the keyword «include». § The include relationship is used to (1) simplify large use case by splitting it into several use cases, (2) extract common parts of the behaviors of two or more use cases. Inclusion base addition
5. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 5 § Extending use case defines optional behavior that is not necessarily meaningful by itself. § Extend relationship is shown as a dashed line with an open arrowhead directed from the extending use case to the extended (base) use case. The arrow is labeled with the keyword «extend». Extension base extension
