Abstract
Decision support systems (DSS) are tools for providing and sharing information, together with the means of using the information to assess the benefit of a decision. An example of a simple DSS system is a financial modelling package available on a microcomputer. However, in large businesses adequate DSS requires backup from a full-scale data processing system. Integrating personal computing and corporate DP is a solution to the problem of providing adequate DSS. Advances in program writing, the use of relational databases, query languages and specific applications all enhance the advantages of such decision support systems. © 1984.
