It is the support system in order to offer the intellectual resource which is needed for the decision making in enterprise being active. Information of various managements is accumulated, the limit of acknowledgment ability of the human is compensated due to the fact that user itself of the decision making person (manager) and the like conversationally does search analysis process simulation, it points to the concept of utilization form of the computer system that quality of decision making and improvement of effectiveness are assured.
It was lectured to the seventies the Scot Mho ton (Scott Morton) of MIT by the doctor, as developmental shape "of the management system (MIS)". There to be a concept that in the root of DSS, "it supports decision making of the manager", at this point in time MIS from "the automation of the decision making by the computer" it differs.
As for the Mho ton MIS and the like when it is the transaction processing type system, it is the system which does definite form decision making, positioning, confronting, DSS assumed that it is concept of new utilization form. On that the Mho ton "system" ESS"for the decision making with the model base" has divided DSS.
When like the corporate model and financial affairs simulation, logical by the fact that the model by the empirical pre-defined equation group is drawn up, "sale 5% increases DSS of former, does the profit how change?", ", when buying cost 10 Yen it increases, some kind of influence appears in sale", the field which analyzes the problem the way. It is the kind of field where as for latter ESS the user in the adding hook selects the data which from the basic type system you collect & accumulate, with the optional section and totals.
Latter DSS (ESS) it madethe typicalexample of EUC , in the eighties, but you used and still the insufficiency could question in the aspect of the selfishness. When it becomes the nineties,utilizedthe technology of the data warehouse the new information type system to appear, it reaches the point where the mechanism which actualizes the concept of DSS in earnest appears,to business intelligence it means to keep being connected.
