Construct an event-oriented EER diagram, a context diagram, and a recording process Level 0 data-flow diagram for the following camera receiving and evaluation process at Clickety-Click Camera Repair. Customers bring in one or more faulty cameras or camcorders for evaluation. A clerk receives the camera(s) and generates a receipt to document the camera(s) received. At this time, customers must pay the minimum charge of $40 per item to have the equipment checked. Note that every camera receiving event is associated with exactly one customer, but a customer can obviously revisit Clickety-Click at a different time with other cameras/camcorders to bee valuated. It is necessary to keep track of the inventory of customer cameras and camcorders that have been received for evaluation. Each received camera/camcorder will eventually be evaluated by a technician. The technician writes up an "evaluation "for each camera/camcorder. Obviously, a technician can perform many evaluations, and newly hired technicians may not have performed any evaluations (until they receive training).After the evaluation is completed, usually within 5 working days, the customer is then given the evaluation report which documents the problem with the camera/camcorder and contains an estimate of how much it would cost to repair it.(Whether or not the customer decides to proceed with the repair, and the subsequent processes, are all beyond the scope of this exercise).
