Define the term database.

A database can be defined as a collection of related data from which users can efficiently retrieve the desired information. A database can be anything from a simple collection of roll numbers, names, addresses and phone numbers of students to a complex collection of sound, images and even video or film clippings. Though databases are generally computerized, instances of non-computerized databases from everyday life can be cited in abundance. A dictionary, a phone book, a collection of recipes and a TV guide are examples of non-computerized databases. The examples of computerized databases include customer files, employee rosters, books catalog, equipment inventories and sales transactions.
