Hi..
Management Information System (MIS) is a subset of the overall internal controls of a
business covering the application of people, documents, technologies, and procedures by
management accountants to solving business problems such as costing a product, service or a
business-wide strategy. Management Information Systems are distinct from regular information
systems in that they are used to analyze other information systems applied in operational
activities in the organization
DSS is a computerized system used for supporting, rather than automating, decisions. A
decision is a choice between alternatives based on estimates of the values of those
alternatives. Supporting a decision means helping people working alone or in a group gather
intelligence, generate alternatives and make choices. Supporting the choice-making process
involves supporting the estimation, the evaluation and/or the comparison of alternatives. In
practice, references to DSS are usually references to computer applications that perform
such a supporting role
A Transaction Processing System (TPS) is a type of information system. TPSs collect, store, modify, and retrieve the transactions of an organization. A transaction is an event that generates or modifies data that is eventually stored in an information system.
