Generate use cases based on the folowing scenario. Chillax Video Store (CVS) runs a chain of video rental stores. Before a video can be put on the shelf for rent, it must be catalogued and entered into the video database. Every customer must have a valid CVS customer card in order to rent a video. Customers rent videos for five days at a time. Every time a customer rents a video, the system must ensure that this customer does not have any overdue videos. If so, the overdue videos must be returned and an overdue fee paid before the customer can rent more videos. Likewise, if the customer has returned overdue videos, but has not paid the overdue fee, the fee must be paid before new videos can be rented. Every morning, the store manager prints a report that lists overdue videos. If a video is returned in damaged condition, the manager removes it from the video database and may sometimes charge the customer.

library contains books, periodicals, and DVDs (no items of other types are available and a given item belongs to only a single category). All these items can be used by the user of the library. Some of the items (books, periodicals, and DVDs) are only reference items, and others can be borrowed by the users. There are two types of users; registered users and temporary users. While registered users can borrow up to 100 items, the temporary users can borrow only 2 items at a time. In the initial work of the EER modeling, your teammates have identified Item, User, and ItemCopy as entities. Which of the following statements are correct about a possible EER model for this set of requirements? The specialization/generalization hierarchy for items that involve borrowing items and reference items has an optional participation constraint. The specialization/generalization hierarchy for items that involve the books, periodicals, and DVDs has a mandatory participation constraint. The user…
