This document defines and provides examples of different types of information systems: Transaction Processing Systems (TPS) are used to process business transactions and maintain data accuracy. Examples include online ticket reservations and flight bookings. Office Automation Systems (OAS) collect, process, store and transmit electronic documents to replace physical work and perform tasks beyond human capabilities. Examples are payroll systems and optical character recognition. Knowledge Work Systems (KWS) help knowledge workers organize tasks and information. Examples include CAD/CAM for design and virtual reality systems for industries like engineering. Decision Support Systems (DSS) analyze business data to facilitate decision making. Examples are analysis and data warehousing systems. Executive Support Systems (
