Define an Information System and Types of Information Systems
An information system comprises the hardware and software components necessary to create, store, manage, share, and maintain data. The type of information system selected depends on the specific needs of the user or the organization. There are three basic types of information systems: transaction information systems, management information systems, and decision support systems ("Types of Information Systems," n.d.).
Decision support systems are indicated for departments that manage strategic planning. For example, a decision support system can offer methods of computing revenue trends, which might provide the necessary data needed to implement an organizational change ("Types of Information Systems," n.d.).

For example, a library uses a transaction support system for its patrons when books are checked in and out.
