Imagine that you are charged with building a knowledge-based system for a car insurance company. Car insurance companies use quite complex grids (we could say rule sets, or knowledge bases) to determine the offers for insurance contracts. Such grids take several things in account, such as customer (that is, the supposed driver) age, gender and living place, as well as car details. The insurance company probably keeps their customer data in a complex database and will know details about cars and the cities where they can place contract offers.
