An Information System (IS) is the system of persons, data records and activities that process the data and information in a given organization, including manual processes or automated processes. Usually the term is used erroneously as a synonymous for computer-based information systems, which is only the Information technologies component of an Information System. The computer-based information systems are the field of study for Information technologies (IT); however these should hardly be treated apart from the bigger Information System that is always involved in.
