A database is a collection of related data that is stored on a computer and organized in a manner that enables information to be retrieved as needed. A field (today more commonly called a column) is a single type of data, such as a person's last name or a person's telephone number, to be stored in a database. A record (today more commonly called a row) is a collection of related fields-for example, the ID number, name, address, and major of a student. A table is a collection of related rows (such as all student address data, all student grade data, or all student schedule data).
