Decision Support SystemsДЄ higher-level class of computerized information systems is decision support systems (DSS). A management information system can also help integrate some of the computerized information functions of a business. Management information systems output information that is used in decision making. The database stores both data and models that help the user interact with, interpret, and apply that data. To access information, users of the management information system share a common database. By requiring people, software, and hardware to function in concert, management information systems support users in accomplishing a broader spectrum of organizational tasks than transaction processing systems, including decision analysis and decision making. MIS are computerized information systems that work because of the purposeful interaction between people and computers.

Management information systems (MIS) do not replace transaction processing systems rather, all MIS include transaction processing.

Knowledge work systems (KWS) support professional workers such as scientists, engineers, and doctors by aiding them in their efforts to create new knowledge (often in teams) and by allowing them to contribute it to their organization or to society at large. Familiar aspects of OAS include word processing, spreadsheets, desktop publishing, electronic scheduling, and communication through voice mail, email (electronic mail), and teleconferencing. Office automation systems (OAS) support data workers, who do not usually create new knowledge but rather analyze information to transform data or manipulate it in some way before sharing it with, or formally disseminating it throughout, the organization and, sometimes, beyond. Office Automation Systems and Knowledge Work SystemsДЄt the knowledge level of the organization are two classes of systems. Because managers look to the data generated by the TPS for up-to-the-minute information about what is happening in their companies, it is essential to the day-to-day operations of business that these systems function smoothly and without interruption.ДЄ systems analyst may be involved with any or all of these systems. Transaction processing systems are boundary-spanning systems that permit the organization to interact with external environments. A TPS eliminates the tedium of necessary operational transactions and reduces the time once required to perform them manually, although people must still input data to computerized systems. Transaction processing systems (TPS) are computerized information systems that were developed to process large amounts of data for routine business transactions such as payroll and inventory. This text uses the terms management information systems, information systems (IS), computerized information systems, and computerized business information systems interchangeably to denote computerized information systems that support the broadest range of user interactions with technologies and business activities through the information they produce in organizational contexts. Notice that the figure presents these systems from the bottom up, indicating that the operational, or lowest, level of the organization is supported by TPS, and the strategic, or highest, level of semistructured and unstructured decisions is supported by ESS, GDSS, and CSCWS at the top. The variety of information systems that analysts may develop is shown in the figure below. Group decision support systems (GDSS) and the more generally described computer-supported collaborative work systems (CSCWS) aid group-level decision making of a semistructured or unstructured variety.

On the strategic level of management we find executive support systems (ESS). Expert systems apply the expertise of decision makers to solve specific, structured problems. Higher-level systems include management information systems (MIS) and decision support systems (DSS). Transaction processing systems (TPS) function at the operational level of the organization office automation systems (OAS) and knowledge work systems (KWS) support work at the knowledge level. Information systems are developed for different purposes, depending on the needs of human users and the business.
