Question 02: Draw a domain model for the following use case (03 Marks)
Use Case: Check Out Books
Primary Actor: Worker
Stakeholders and Interests:
- Worker: wants fast, and easy check out of books.
- Patron: wants fast check out, and does not want to be charged for books they did not check out.
- Library: wants fast check out of books, and wants to make sure that all books that leave the
library have been checked out. Wants to allocate books fairly.
- Government: wants to protect investment in books and keep costs down. Wants to promote
learning and citizen happiness.
Preconditions: The Worker has been authenticated.
Success Guarantee (Postconditions): The System remembers that the Patron has checked out the
books.
Main Success Scenario (or Basic Flow):
1. The Worker tells the System the identity of a patron who wishes to check out books.
2. The System confirms that the patron is allowed to check out books, and remembers the
patron's identity.
3. The Worker tells the system the identity of a book this patron is checking out.
4. The System confirms that the book can circulate, calculates the due date based on whether the
patron is a faculty member or a student, and records that the patron has checked out this book,
which is due on the calculated due date, and makes that information available from the library
catalog.
5. The System tells the Worker the due date (which also confirms that the book has been checked
out).
The Worker repeats steps 3-5 until indicates done.
Extensions (or Alternative Flows):
2a. If the patron is not allowed to check out books because they have violated some library
policy (for example, if the patron has not paid their university bill or library fines):
1. The System tells the Worker that the patron is not allowed to check out books and the reason
for this prohibition.
2. The use case ends.
4a. If the book that is being checked out is non-circulating:
1. The System tells the Worker why the book is non-circulating.
2. The use case continues from step 3 in the main success scenario.
Solution
