Every organization that uses a computer system to maintain its operational and management information does so using a collection of interrelated files called a database. Every file in a database consists of a template called a record template, which is used to create individual records of information. Each record contains a collection of predetermined fields into which the record’s information is entered. A simple equivalent to a computer file is a physical address book which contains the names, addresses and telephone numbers of your friends and acquaintances. Just as in a computer file, each record in the address book has the same format — one line for name, three lines for address, one line for post code and one line for telephone number.
