1. Requirements

The database under construction will be used in conjunction with a video game retailer who is converting to a primarily online retailer. Their

website will be called BigMegaGamingDatabase.com. This company offers for purchase to members video games for all four relevant gaming

platforms (Xbox, PS3, Wii, and PC). Other gaming accessories, such as headsets, controllers, wires, etc. will also be sold by the store.

Anyone can browse the store, but one must be a member to make any purchases. If not a member already, upon checkout the guest will be

required to create a member profile. Members sign up by entering their full first name, middle initial, last name, any suffix/prefix, email

address, and primary phone number. Upon sign up, members will also be forced to choose a Member ID and password. Member IDs must be

unique across all members. They will also need to add a shipping address, billing address, credit/debit card type, name as it appears on card,

number, expiration date, security code, and credit card nickname, alternate phone numbers, birthdate, and gender. No other method of

payment will be accepted other than credit/debit card. The user can then choose from the selection of inventory to make a purchase.

There will also be an option to become part of the mailing list. Members are automatically added to the mailing list (unless they deselect that

option during sign up). To become part of the mailing list (as well as active their membership) the user must enter a valid email address and

then confirm that the address is valid by clicking a link in an email that will be immediately sent to the account that was provided.

Inventory is split into two separate areas: video games and accessories. Video games are associated with item number, platform, game title,

producer, maturity rating, year released, the edition, quantity in stock, retail price, and shipping category (small, medium, or large). The

shipping category information will be used to determine the shipping cost for each item. Accessories are associated with item number,

platform, accessory type, manufacturer, model name, model number, quantity in stock, retail price, and shipping category (same as above).

When a member creates a transaction, the following data will be recorded: Date, Member ID, order number, order total, game/accessory

number, quantity, shipping cost, and tracking number. Order numbers are not repeated and are unique.

Once an order is received, the appropriate items are allocated and their associated quantities are reduced by the number ordered. This

completes the sales cycle.

7. Sample Queries

To check on our average shipping costs for after a certain date:

SELECT Avg(ShipCost)AS AVGSHIPCOST

FROM Orders

WHERE DateTime > '08-MAY-2012'

Output:

AVGSHIPCOST

-----------

9.98

28


To view the customers that have ordered more than one item from the store:

SELECT p.MemberID, Sum(o.Qty) AS SumQty

FROM Profile p, Orders o

WHERE p.MemberID = o.MemberID AND o.Qty > 1

GROUP BY p.MemberID

ORDER BY Sum(o.Qty) DESC

Output:

MEMBERID SUMQTY

------------ ----------

FlynHawaiian 4

AgentBauer 3

AgentGibbs 2
