A small appliances rental company in CT has several branches. It is renting TVs and other small home appliances to its customers. New appliances are recorded in the system before they are offered for rent. The first time a customer rents an item she/he needs to provide the necessary personal and payment card details. A deposit equal to the double amount of the estimated total of the rental bill (including insurance premium for possible damage) is charged to the card on the first day of a rental. Upon return of the appliance the actual price for the rental is charged to the customer card and the deposit is returned to the customer. A text message to customers who are overdue for more than 3 days is generated every day. The current system is run on old standalone PCs that are not connected in a central system. The owner of the company requested a software expert to develop a new centralized system that keeps track of all rentals.
