UML diagram:

You have been contracted to develop a computer system for a university library.

The library holds many types of documents for its users which are students, faculty, and staffs of the university. Some of those documents are books, journals, and conference proceedings.

Documents such as journals are for short-term loan only (i.e 10 working days). Other documents such as books may be borrowed for up to six months for a student and a year for a faculty or a staff member. The maximum items that a faculty or staff member can borrow are 12 while it is only 6 for students.

It is essential that the system keep track of the number of copies of books when books are borrowed and returned. The system should produce a reminder when a book borrowed by a user is overdue.

A user should be able to extend the loan if the borrowed item is a book and others have not reserved it. The system should allow users to search for a document based on a particular title, by a particular author or by certain keywords. Any user can search for documents hold in the library. To be able to borrow documents from the library, the user must be registered.

1. Identify some of the obvious actors of the above library system. Must identify at least three actors.

2. Identify and document three main use cases of the library system. Write a short description of these use cases. Use case description must have a name, participating actors, the entry condition, the exit condition and the flow of events.

3. Draw a sequence diagram for at least a usage scenario of a user (Dr. Shi, a faculty of the university) returning a book successfully. Make sure the sequence diagram is drawn with the correct UML notations.
