Scenario:

Students of the library can access the library's digital resources online using the library management system. Online users can look up, reserve, and check out books. Moreover, users have the option to seek holds on presently checked-out books as well as renew their borrowed books. Users will be informed by the system of their due dates and any associated late fines.
