Database ''Tables'' provide the most basic level of data structure in a database. Each database can contain multiple tables and each table is designed to hold information of a specific type. For a example, a database may contain a ''customer'' table which contains the name, address and telephone number for all the customers of a particular business. The same database may also include a ''products'' table used to store the product descriptions with associated product codes for the items sold by the business.
