Draw a physical level 0 DFD for the following system and compare it with the logical model that you created in Chapter 5. A Video Store (AVS) runs a series of fairly standard video stores. Before a video can be put on the shelf, it must be catalogued and entered into the video database. To rent a video, every customer must have a valid AVS customer card. Customers rent videos for three days at a time. Every time a customer rents a video, the system must ensure that he or she does not have any overdue videos. If so, the overdue videos must be returned and the customer must pay a fine before renting more videos. Likewise, if the customer has returned overdue videos, but has not paid the fine, the fine must be paid before new videos can be rented. Every morning, the store manager prints a report that lists overdue ideos; if a video is two or more days overdue, the manager calls the customer to remind him or her to return the video. If a video is returned in damaged condition, the manager removes it from the video database and sometimes charges the customer.
