Consider the following problem statement for
answering questions (14-17):
Students use the library system to reserve a
book, borrow a book, return a book, or extend
loaning of a book. When borrowing a book, the
student has to locate the book. Sometimes, a
student cannot extend loaning of a book
because limits are exceeded. The librarian
updates catalog and sets borrowing limits for
different user categories.
14. Which of the following uses cases is
possibly an extension use case?
a. Set borrowing limits
b. Borrow a book
c. Exceed limits
d. Update catalog
e. extend loaning of a book
15. Which of the following uses cases is
possibly an inclusion use case?
a. Reserve a book
b. Extend loaning of a book
c. Locate a book
d. Exceed limits
e. Borrow a book
16. How many actors would you identify in
this problem statement?
a. 5
b. 4
c. 3
d. 2
e. 1
17. Assume that borrow a book has been
identified as a base use case. What
priority rank would you give to this use
case? Assume that rank 1 represents
the highest priority and rank 5
represents the lowest priority.
a. 5
b. 4
c. 3
4|4
d. 2
e. 1
