. A library has books, journals, and periodicals that it loans to its users. All library material has an

accession number which is a unique identifier and a price. In addition, a book has a title, publisher, year

of publication, edition, and authors. Journals have journal name, volume number, issue number and year

of publication. Each article in a journal has a title and authors. A periodical has a name and date of

publication. The library keeps one or more copies of each library item (book, journal, periodical). Copies

of all library material can be loaned to users. Reference-only material is loaned for 2hrs and can’t be

removed from the library. Other material can be loaned for 2 weeks. For every loan, the library records

the user, the loan date and time, and the return date and time. For users, the library keeps their name,

address, and cell phone number. If a user loses a loaned item they are made to purchase it, however, if

the user delays with the loaned item they are finned according to the number of days after the return

date. At the moment the fine is R10 per day.
