Q4)- Read the following scenario and answer the questions below.

“A university library system needs to be built in order to handle the bookkeeping aspects of a

library and provide user-browsing facilities. The system allows borrower to search for a book on

a particular topic or by a particular author. The borrower should then be able to check if the book

is on loan and if so to reserve the book. If a student wants to borrow or return a book, the library

staff should enter the student ID to be searched. If student search is successful, the staff will enter

the book ID, and if the book is available it can be borrowed. When a student wants to return a

book, the staff checks the report data for any pending fine and if no fine is pending the book can

be returned.”
