2.6 Summary

 Information systems can be grouped into business function categories; however, in the
real world information systems are typically integrated combinations of functional
information systems.
 Management Information Systems comprise many sub-systems and are influenced by the
organization’s structure, activities, risk profile, and technological capabilities.

 Transaction Processing Systems (TPS) are cross-functional information systems that process
data resulting from the occurrence of business transactions.

 A Decision Support System (DSS) is an interactive computer-based system, which helps
decision-makers utilize data and models to solve unstructured problems.
 An ‘MIS’ is a planned system of the collecting, processing, storing and disseminating data
in the form of information needed to carry out the functions of management.
 Executive Support Systems (ESS) supply the necessary tools to senior management. The
decisions at this level of the company are usually never structured and could be described
as “educated guesses.”
 The various types of systems in the organization have interdependencies. TPS are a major
producer of information that is required by the other systems which, in turn, produce
information for other systems.

 Enterprise Systems (ES) are large-scale, integrated application-software packages that use
the computational, data storage, and data transmission power of modern Information
Technology (IT) to support processes, information flows, reporting, and data analytics
within and between complex organizations.
