'MIS'

- is a planned system of collecting, processing, storing and disseminating data in the form of information needed to carry out the functions of management. According to Phillip Kotler "A marketing information system consists of people, equipment, and procedures to gather, sort, analyse, evaluate, and distribute needed, timely, and accurate information to marketing decision makers." (Kotler, Phillip and Keller, Kevin Lane; Marketing Management, Pearson Education, 12 Ed, 2006)

The terms MIS and information system are often confused. Information systems include systems that are not intended for decision making. MIS is sometimes referred to, in a restrictive sense, as information technology management. That area of study should not be confused with computer science. IT service management is a practitioner-focused discipline. MIS has also some differences with Enterprise Resource Planning (ERP) as ERP incorporates elements that are not necessarily focused on decision support
