Redesigning the Customer Database
Software skills: Database design; querying and reporting
Business skills: Customer profiling
Dirt Bikes U.S.A. sells primarily through its distributors. It maintains a
small customer database with the following data: customer name, address
(street, city, state, zip code), telephone number, model purchased, date of
purchase, and distributor. These data are collected by its distributors when
they make a sale and are then forwarded to Dirt Bikes. Dirt Bikes would like
to be able to market more aggressively to its customers.
The Marketing Department would like to be able to send customers email notices of special racing events and of sales on parts. It would also like
to learn more about customers’ interests and tastes: their ages, years of
schooling, another sport in which they are interested, and whether they
attend dirt bike racing events. Additionally, Dirt Bikes would like to know
whether customers own more than one motorcycle. (Some Dirt Bikes
customers own two or three motorcycles purchased from Dirt Bikes U.S.A.
or other manufacturer.) If a motorcycle was purchased from Dirt Bikes, the
company would like to know the date of purchase, model purchased, and
distributor. If the customer owns a non–Dirt Bikes motorcycle, the company
would like to know the manufacturer and model of the other motorcycle (or
motorcycles) and the distributor from whom the customer purchased that
motorcycle. Dirt Bikes’s customer database was redesigned so that it can
store and provide the information needed for marketing.
Case Questions:
Develop the following queries and reports that would be of great interest to
Dirt Bikes’s marketing and sales department.
1- Create a report of customers and motorcycles model grouped by
manufacturer.
2- Create a query about Dirt Bikes customers who attend racing events.
3- Create a query of the customers who have more than 12 years of
education.
