Hi I just need to draw the ERD with all the relationships I'll upload my case study and I'll upload an example how I need it to be done
• · Create a fully expanded ERD based on the information in the following narrative. Business Narrative Aussie Wine Tours (AWT) conduct tours of the wineries of Victoria's Yarra Valley wine region. Each tour is run on a single day. Currently, there are several wine tours including The White Wine tour, The Red Wine tour and The Sparkling Wine tour. The Red Win Tour is a very popular tour and has often run 3 or 4 times in a single month. The tour schedule depends upon the availability of the wineries, the availability of the tour leaders and the public interest. Each tour takes usually takes around 6 hours to complete and is led by one or more of AWT's well-renowned wine experts. Each tour has a 'current price'. However, due to various market forces, prices have been rising over the past couple of years. For example, last year the Red Wine Tour was $170 but now it's the current price is $200. No two events for the same tour can occur on the same day. (e.g. The Red Wine Tour cannot be conducted twice on the same day). AWT have many satisfied customers, many of whom have attended multiple wine tours over the years. Each customer has a customer id, name, address and contact phone number. AWT usually plan and advertise wine tour details and dates about 6 months prior to the running of each tour. Customers usually ring AWT to make bookings for their wine tour. Each booking stored in the AWT system is for a single person. (E.g. A husband and wife attending the same tour event will have two bookings created for them. Each booking is for a single customer). AWT have a number of printed wine tour brochures –one for each of the different wine tour (E.g. A 4page printed glossy brochure that has photos and details of the Red Wine Tour). People often ring up or email AWT and request a brochure. Brochures are only sent to customers. If the person requesting a brochure is not already a customer, then AWT create a new customer by assigning a customer id and recording the person's name, address and phone number. When a brochure is requested, AWT record the date of the request. After the brochure is mailed to the customer, AWT record the date that the brochure was sent. Obviously, a customer who requests a brochure is not under any obligation to make any bookings. A customer makes payment(s) for each booking. Each payment made is for a single booking. AWT record the amount of the payment, the date of the payment, the type of payment made (cash, credit card or cheque) and which booking the payment is for. Some customers may two or more payments for single booking (e.g. the tour price is $200 a end the customer makes two payments $120 and $80.) Sometimes (though rarely), a customer makes a payment for an amount larger than required. AWT simply record the amount of the payment. (You simply have to record the amount of the payments made. You do not need to concern yourself with how refunds or payment transfers may occur). 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 a mixture of the type of tour, the whim of the wine expert leading the event and availability of stock. On the day of the event, each participant may choose a maximum of two gifts. AWT records which gifts are chosen by each booked customer. Obviously, a customer has the right to not select any gifts while attending a tour. Note: You are not expected to limit the number of gifts selected by a customer to 2. This is beyond the scope of an ERD. Such a restriction would normally be programmatically solved using a Stored Procedure, Trigger or some other programming technique).
