3 Level pyramid model diagram - Information systems types

A three level pyramid model of different types of Information Systems based on the type of decisions taken at different levels in the organization. The first level represents transaction processing systems focused on operational decisions. The second level represents management information systems focused on tactical decisions. The third level represents executive information systems focused on strategic decisions. "Information system (IS) is the study of complementary networks of hardware and software (see information technology) that people and organizations use to collect, filter, process, create, and distribute data. The study bridges business and computer science using the theoretical foundations of information and computation to study various business models and related algorithmic processes within a computer science discipline. Computer information system(s) (CIS) is a field studying computers and algorithmic processes, including their principles, their software and hardware designs, their applications, and their impact on society while IS emphasizes functionality over design. Any specific information system aims to support operations, management and decision making. In a broad sense, the term is used to refer not only to the information and communication technology (ICT) that an organization uses, but also to the way in which people interact with this technology in support of business processes."
