Safe Rentals, a private rental company which rents out vehicles (cars and vans). The Company has various outlets (garage/offices) throughout the city of Toowoomba. Each outlet has a number, address, phone number, fax number, and a manager who supervises the operation of the garage and offices at each site. Each site is allocated a stock of vehicles for rent; however, individual vehicles may be moved between outlets, as required. Only the current location for each vehicle is stored. The registration number uniquely identifies each vehicle for rent and is used when hiring a vehicle to a client. Clients may rent vehicles for various periods of time (minimum 1 day to maximum 1 year). Each individual rent agreement between a client and the Company is uniquely identified using a rent number. Information stored on the vehicles for rent include: the vehicle registration number, model, make, engine size, capacity, current mileage, date registration due, daily rent rate, and the current location (outlet) of each vehicle. The data stored on a rent agreement includes the rent number, the clients number, name, address and phone number, date the client started the rent period, date the client wishes to terminate the rent period, the vehicle registration number, model and make, the mileage before and after the rent period. After each rental a member of staff checks the vehicle and notes any fault(s). Fault report information on each vehicle is stored, which records the name of the member of staff responsible for the check, date checked, whether fault(s) where found (yes or no), the vehicle registration number, model, make and the current mileage at the time the fault is found. The Company has two types of clients: personal and business. The data stored on personal clients includes the client number, name (first and last name), home address, phone number, date of birth and driving license number. The data stored on business clients includes the client number, name of business, type of business, address, and telephone and fax numbers. The client number uniquely identifies each client and the information stored relates to all clients who have rented in the past and those currently hiring a vehicle. Information is stored on the staff based at various outlets including: staff number, name (first and last name), home address, home phone number, date of birth (DOB), gender, National Insurance Number (NIN), date joined the Company, job title and salary. Each staff member is associated with a single outlet but may be moved to an alternative outlet as required, although only the current location for each member of staff is stored.
