It uses rules and models for processing data, to support various managerial levels, ranging from top executives to mangers, in their decision-making.

The vast majorities are semi structured. This means that the DSS is aimed at the area where most problems are found.

The concept of a Decision Support System (DSS) emerged in the 1970s following developments in IT which allowed the interactive use of computer technology. The DSS concept reflected dissatisfaction with previous inflexible modeling approaches which did not allow management intervention in problem solving. The early definitions of DSS emphasized the role of DSS as flexible systems combining database and model components aimed at less structured decisions. These modeling and database components are under the control of the user through an interface or dialogue system.

Typical information that a decision support application might gather and present includes: inventories of information assets (including legacy and relational data sources,...
