Foundations and Applications of MIS presents a unique systems theory approach to management information system (MIS) development. It covers an outline of the approach, providing a theoretical foundation for MIS from the systems theoretic viewpoint before presenting practical feasibility of the approach using applications ranging from a transaction processing system to a solver system. The author also describes his newly developed extended Prolog programming language, which takes full advantage of the mathematical framework employed. High-level mathematics is combined with sophisticated software engineering in this approach to address the practical problem area of designing MISs; it is the synergy of these two areas with underlying systems thinking that gives this book its unique identity.The book assumes a working knowledge of elementary set theory, logic and familiarity with some systems concepts such as automation models. Senior and graduate students, researchers in management information systems, systems engineers and systems scientists will find this book useful.
