Hello, I need nelp with the following problem below, thank you!

.

A library wishes to computerize its operations. The main feature of the system is the card catalog that allows patrons to search the collection by subject, author, key word, and title. The user interface for this system is critical as it will be the most used feature by the patrons. The circulation system allows items in the collection to be checked out. Undergraduate students may check out an item for two weeks, graduate students may check out items for eight weeks, and faculty members may check out an item for a semester. Items are restricted from being checked out if a faculty member has reserved the item for a class or if the item belongs to a special collection. Such items are checked out for only 2 hours, from the reserve desk. If an item is checked out by one patron and is needed by another patron, the item can be recalled. A notice is sent to the patron with the item and the due date is changed to one week after the notice is sent. Alternatively, the item can be reserved for check out by a patron and the patron notified when the item is returned. Such items reserved for check out are held only for one week and then returned to the stacks if not collected. An item that is checked out can be rechecked if it is not recalled or reserved by another patron. People not connected to the university may apply to be patrons with the same limits placed on undergraduate students but may not request interlibrary loans. Non-matriculating students are treated the same as undergraduate students. Employees of the university are treated as non- matriculating students. Part II. (20 points each, answer 3 of the following 4 questions) Select an architectural model that would be suitable for the system in Part I. Describe and overview of the system using that model. 1.
