There is a schema example below: (From A first course in database system)
Product (maker, model,type)
Pc (model, speed, ram, hd, rd, price)
Laptop (model, speed, ram, hd, screen, price)
Printer (model, color, type, price)

...basicly any logical statement...and return the right references based on
searching
