Chimney Sweep is a retail store that sells fireplaces and fireplace tools. It knows the buying behavior of all of its clients because it maintains a database, so when it needs to run an advertisement, or it needs to decide what items to put on sale to draw in customers, it can use this data to help make decisions.
