TPS are typically a major source of data for other systems, especially MIS and DSS. TPS are operational-level systems that collect transaction data. Examples of these are payroll or order processing that track the flow of the daily routine transactions that are necessary to conduct business. TPS provide data that are required by MIS and DSS, although these systems may also use other data. DSS not only use data from TPS but also from MIS. MIS rely heavily on data from TPS. ESS isprimarily a recipient of data from lower- level systems. They obtain most of their internal data from MIS and DSS. Decision support systems (DSS): %u2022 Serve middle managers %u2022 Support nonroutine decision making %u2022 Often use external information as well from TPS and MIS Model driven DSS E.g.
