Draw A Level 0 data flow diagram (DFD0 for the following scenario:

Aventus 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. Every customer must have a valid AVS customer card in order to rent a video. Customers rent videos for three 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 over-due fee paid before the customer can rent more videos. Likewise, if the customer has returned over-due 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 two or more days over-due, 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 may sometimes charge the cus-tomer.
