2. Supermarkets today
Think of a journey through the modern supermarket. You enter a brightly lit, welcoming store, each shelf laden with the widest choice of food and goods for you to buy.
A typical outlet will have about 20,000 different items. Each with its own price and 'special deals' - "buy one get one free!", "half price" ... how is all this tracked and kept up to date?
Once the next few pages we will look at the systems which make this all possible.
