Question

In order to borrow an item from the library, a member first enters the membership card into a card reader of the library. The system retrieves the membership details and contacts the university system UniSys to find if the member is an active staff or student. If not, the system does not allow the member to borrow any item from the library and terminates the function. Otherwise, the system asks the member to place the item in the scanner. Once the member does this, the system gets the item details and its type. It also checks if the item is available for loan. The system also finds out the total items already borrowed but not returned. If the item is available for loan, and the total item borrowed but not returned is less than 5, it makes a loan for the member. The item is included in the membership account with the borrowing date and due date for return. The system then increments the total borrowed items by 1, and it makes the item unavailable for other members. The system also decrements the total items reserved of the member if the item was reserved by the member. The member has also choice to request for extended loan time for one more week. If the item was not reserved, one more week is added with the original return date. Finally, it creates a receipt of the loan, and releases the security code of the item. The receipt includes information such as membership number, item call number, loan date, and return date..... in use case diagram
