Lab$3\_$Worksheet: Use Case Diagram $($Part $2)$

Objective

The objective of today's session is to familiarize yourself with the different types of relationships used in use case diagrams, namely, the inclusion, extension and generalization relationships. As you cover these concepts, you should be ready to draw your first complete use case diagram. You will be guided throughout the process with some tips which will help you create any use case diagram in the future.

Exercise $1$:

Draw the following use case diagram with StarUML.

Exercise $2$:

In the previous use case diagram you created for the Library Administration System, what type of relationship can you use to show that the librarian can do whatever a library patron can $($with some extra additions$)?$ Show that relationship and refine the diagram accordingly.
