What are the types of information systems and the characteristics of each type

There are three types of information systems: transaction processing systems, management information systems, and decision support systems.

(1) Transaction processing systems (TPS) are used primarily to support the daily activities of operational level personnel.

(2) Management information systems (MIS) need to encompass the transaction processing systems in the organization and provide a comprehensive form of data internally, as well as the general scope and large scope of data from external organizations.

(3) Decision support systems (DSS) can get information from MIS to help managers make good decisions.
