Autombile Sales Database

Application description:

The application is an automobile company, such as General Motors, Ford, Toyota, or Volkswagen (or maybe a company from yesteryear like Studebaker, Hudson, Nash, or Packard).

In our hypothetical company, it has been decided to redesign a major part of the database that underlies company operations. Unfortunately, the manager assigned to solicit database design proposals is not very computer literate and is unable to provide a very detailed specification at the technical level. Fortunately, you are able to do that. The company needs to keep quite a bit of data, but we shall focus on the following aspects of corporate operations.

• vehicles. Each vehicle as a vehicle identification number (VIN). Lots of stuff is encoded in real VINs (they are well described on Wikipedia), but you can just make them up if you want.

• brands: Each company may have several brands (for example, GM has Chevrolet, Pontiac, Buick, Cadillac, GMC, Saturn, Hummer, Saab, Daewoo, Holden, Vauxhall, and Opel and Volkswagen has Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Skoda, and SEAT)

• models: Each brand offers several models (for example, Buick’s models are the Enclave, LaCrosse, and Lucerne, and Mercury’s models are the Mariner, Milan, Sable, and Grand Marquis). Each model may come in a variety of body styles (4-door, wagon, etc.)

• options: We’ll stick to color, and maybe engine and transmission.

• dealers and customers: dealers buy vehicles from the manufacturer and sell them to customers. We’ll keep track of sales by date, brand, model, and color; and also by dealer. Note that a dealer may not sell some of the car company’s brands. Dealer’s keep some cars in inventory. Some of course, are already sold, but the dealer still keeps track of that fact.

• suppliers: suppliers supply certain parts for certain models

• company-owned manufacturing plants: Some plants supply certain parts for certain models; others do final assembly of actual cars.

• customers: In reality, lots of demographic data are gathered. We’ll stick to name, address, phone, gender, and annual income for individual buyers. The customer may also be a company (e.g. Hertz, Avis, or other companies that maintain corporate fleets, but we’ll skip that).

• We’ll skip data on corporate finance, pending bailouts, bankruptcy status etc. Not that these data are unimportant, but we need to keep the project within bounds.

Queries:

You should run a number of test queries to see that you have loaded your database in the way you intended.

Construct and execute SQL queries for the following:

• Show sales trends for various brands over the past 3 years, by year, month, week.

• Find the top 2 brands by dollar-amount sold in the past year.

• Find the top 2 brands by unit sales in the past year.

• In what month(s) do convertibles sell best?

• Find those dealers who keep a vehicle in inventory for the longest average time.
