Business Narrative
Aussie Wine Tours (AWT) conduct tours of the wineries of Victoria's Yarra Valley wine region. The tours take place on the last Sunday of each month. Currently there are seven alternative wine tours. The Old Wineries tour, the White Wine tour, the Red Wine tour, the Sparkling Wine tour and so on. Not all tours are offered on each of the Sundays. The schedule depends upon the availability of the wineries, the availability of the tour leaders and the public interest.
Each wine tour event runs for 3-6 hours. Each wine tour event is lead by a single wine expert.
No two events for the same tour can occur on the same day.
AWT have a number of printed wine tour brochures - one for each wine tour on offer. Whenever a brochure is sent AWT records the date that brochure is sent. The person the brochure is sent to is added to the AWT's list of customers and is assigned a customer number. AWT also record the customers name and address. Obviously, not all customers who request a brochure participate in any of the wine tours.
Many customers book places on a wine tour event. Each wine tour event has a price. Wine tour events sometimes include a meal. This obviously increases the price of such an event. AWT record which tour event a customer has booked on and whether payment has been made (customers may not make partial payments). Each customer attending a wine tour event must have a separate booking. E.g. A husband and wife attending a tour event will require two bookings.
AWT have a number of gifts available for participants attending tour events. Generally, three or four gifts are offered to participants of a tour event. The gifts on offer are often decided by the wine expert leading the event. On the day of the event, each participant may choose a maximum of two gifts. AWT records which gifts a participant chooses on a particular tour event. (Note: You are not expected to limit the number of gifts selected by a customer. This would normally be programmatically solved using a Stored Procedure, Trigger, or some other programming technique).
