Databases are a tremendously powerful tool. We're still wrapping our heads around how to use them exactly on our website, but their abilities are well documented. Every online store has a database with all its product information, customer information, order and shipping information, stored with maximum efficiency to make finding that information and sending it out as quick as possible. A database stores all that information and provides any piece or pieces on demand to help build webpages. The beauty of this system is that a user can then provide some form of electronic ID via a login, and the user can then see a customized page just for them, for example they could review an order they have placed.
