There are 4 kinds of different of systems that support the different levels of decisions:

  1. Management Information Systems (MIS)

 

  1. Decision-Support Systems (DSS)

 

  1. Executive Support Systems (ESS)

 

  1. Group Decision-Support Systems (GDSS)

MIS

This is a general term for the computer systems in a firm that provides  information about the business operations of the firm. Usually, in a large firm or company, it refers to a central or centrally-coordinated system of computer expertise and management. (http://searchdatacenter.techtarget.com/definition/MIS )

 

DSS

Techopedia defines DSS as “a computer-based application that collects, organizes and analyzes business data to facilitate quality business decision-making for management, operations and planning. A well-designed DSS aids decision makers in compiling a variety of data from many sources: raw data, documents, personal knowledge from employees, management, executives and business models. DSS analysis helps companies to identify and solve problems, and make decisions.)

GDSS

DeSanctis and Gallupe have stated that a GDSS is “an interactive computer-based system to facilitate the solution of semi structured and unstructured tasks by a group that have joint responsibility for performing it.”
