Information system, an integrated set of components for collecting, storing, and processing data and for providing information, knowledge, and digital products.

Information systems use data stored in computer databases to provide needed information. A database is an organized collection of interrelated data reflecting a major aspect of a firm’s activities. Information systems capture data from the organization (internal data) and its environment (external data).

There are various types of information systems, for example: transaction processing systems, decision support systems, knowledge management systems, learning management systems, database management systems, and office information systems.
