Apple Inc. There are four main categories of systems from a constituency perspective. The transaction processing systems (TPS) are basic business systems that serve the operational level of the organization by recording the daily routine transactions required to conduct business. Apple Incorporated uses smart phone credit card readers and mobile transaction processing systems. Management information systems (MIS) serve middle managers’ interests by providing current and historical performance information to aid in planning, controlling, and decision making at the management level. Apple Incorporated uses their warranty records and performance/sales records to aid in the management information systems. Decision-support systems (DSS) also known as business intelligence systems, help managers with non- routine decisions that are unique, rapidly changing, and not easily specified in advance. The five types of decision support systems are document driven, knowledge driven, model driven, data driven, and communication driven. The executive support systems (ESS) provide a generalized computing and communications environment that help senior managers address strategic issues and identify long-term trends in the firm and its environment. Apple Incorporated uses non-routine decisions, data from internal and external sources, and long-term trends to help aid in executive support systems.
