Supermarket : Introduction

Supermarkets sell food and other household products to customers. Most supermarkets are very large stores which stock a wide range of products. Customers select the items that they want to buy from shelves as they go around a store. After a customer has selected the items he wants to purchase he takes them to a till where he must pay for them.

A supermarket needs an information system which can :

1.  Accurately calculate the cost of a customer's purchases.
2.  Try to ensure that the store does not run out of products that customers want to buy.
3.  Take the payment for goods from customers.

In most areas of the country customers can choose to shop at several different supermarkets. Therefore the supermarket owners must compete with each other to attract new customers and to keep their existing customers.
