Decision Making System

The decision making is an important manager’s activity. It is a permanent and continuous activity performed by the managers. Besides their major functions, the managers take all the time managerial decisions concerning various problem and of various nature. Generating of reports does not automatically solve problems and is not decision making. Anywhere throughout the world, as well as in Bulgaria, the managers of commercial, industrial and financial establishments try to find a way for efficient use of information. During the past years large operative databases have been accumulated, like information of customers, suppliers and competitors. Business necessitates the use of information at a very detailed level. Terms like Data Warehouses, Decision support systems, Data mining are often used to describe one and the same thing. But in fact each of them describes a specific element of the overall approach of decisions support. The Decision Support System (DSS) is a computer-based system designed to assist those who make decisions and face badly structured problems through the data’s direct interaction with the analytical models. The classic means of implementation of decision support systems are very closely related to the means of development of databases management systems. There are three modules in the DSS allowing the analysis of information. It is orientated to specific problems and is closely connected to the information needs of the decision carrier. They use a dialogue, an application of different models and a graphical presentation of information. DSS have three major components: database, models-base and consumer’s interface.
