This document discusses concepts and principles of management information systems (MIS) and how they can support decision making and organizational functions. It defines key elements of information systems including data, hardware, software, telecommunications, and people. Effective information systems capture, transmit, store, retrieve, manipulate and share data to build organizational knowledge and support various levels of management decision making from strategic to operational.
