There exist two areas in Decision Support System. The one is the business area where the application logics are common property of the organization and should not be hold by a special person as black-box. e.g. Profit Planning. Cost Accounting. Production Planning etc. The another area would be afforded to be kept closed as black box. Responding “What-if” needs in the former area, current approaches which, in conclusion, require end-users utilizing of computer language, however efficiently it works, had difficulties. Thinking the computer jobs performed by individuals, the consolidating of them become more serious. A breaking-through was required to diminish the semantic gap between end-users and their computer processes. Also maintenance of application system brought by “What-if” is a big problem in DSS. A breaking-through was done by MATPLAN based on the new technology: STRUCTURED MATRIX—hierarchical table including datas and their processing logics, with the expression of mutual relations. You will find various suggestions for new system approach towards the 21 century in this paper.
