S-Cars is a limousine rental company that uses a paper-based booking system. It has 12 limos that seat between 7-20 passengers. The company employs 15 freelance drivers who are paid monthly. Customers can book limos up to 90 days in advance for morning, afternoon or evening sessions. The new owner is updating the company's archaic paper-based booking system.

3. Scenario S-Cars is a company which hires out stretch limousines, complete with uniformed chauffeurs, for special occasions. S-Cars currently has a fleet of 12 limos the smallest of which can take seven passengers the largest 20. The limos are hired out in sessions. In general there are three sessions in a day. The morning session starts at 7 am and finishes at 12 midday, the afternoon session lasts from 1 pm to 6 pm and the evening session from 7 pm to midnight. Earlier starts can be negotiated depending on the availability of limos and drivers. If customers book consecutive sessions they can negotiate with the driver as to when the hour break is taken. The firm employs 15 freelance drivers who are paid on a ‘number of sessions’ basis. Their rates vary from £40 to £80 a session and their wages are paid by the firm at the end of each month. Customers may hire more than one car or driver for special occasions (eg weddings or West End trips) and many customers book limos regularly. The first time customers make a booking they are given a client number which consists of the first three letters of their surname plus a four figure number. Customers quote their number when they make further bookings. Regular customers can negotiate discounts. Limos can only be booked up to 90 days in advance but drivers are assigned on the morning of the hire. A customer rings up or comes to reception. If they are an existing customer you look up their details in the card index file. If they are new, you ask them for their details and create a card. You are the new owner of S-Cars and are shocked to find the company uses this archaic paper-based system. bookings drivers customers limos bookings bookings ONE customer(s) can make ONE booking(s) MANY MANY ( ) ( ) ONE booking(s) can be for ONE limo(s) MANY MANY ( ) ( ) ONE booking(s) can be for ONE driver(s) MANY MANY ( ) ( ) drivers limos bookings bookings bookings_limos bookings_drivers
