Decision Support System (DSS) is a computer based system which uses analytical models, specialized databases and aids the decision makers in making complex decisions in an organization. In the old days, a group of professional people in a company used to consider various factors and variables while taking a complex decision. This herculean task has now been made easy with the introduction of various DSS tools. These tools help the decision makers in making a right decision. However, the final choice of taking the decision remains with the assigned decision maker. Most of the organizations now-a-days use DSS tools so as to speed up the decision making process which eventually help in the growth and development of their business.

It is the part where when can enter commands and information to the system. Knowledge Management Component: This component is the knowledge base of an organization which provides information among the complex data in the system.
