Transaction Processing Systems (TPS) process business transactions by collecting, modifying, and retrieving transaction data. TPS ensure atomicity, consistency, isolation, and durability of database transactions. Office Automation Systems (OAS) collect, process, store, and transmit electronic messages to support office functions like word processing, spreadsheets, and databases. Decision Support Systems (DSS) help decision makers compile useful information to identify and solve problems and make decisions through interactive software. Executive Support Systems (ESS) allow executives to access summarized reports from all levels of an organization to gain direct access to performance information.
