Complexity in Modeling and Analytic Use of Computers
Several computerized systems of enormous power are available to IIASA, often at almost no cost. Indeed, two or three, at least, are here now waiting to be used. Yet no one is using them. Nor is this… Expand
A Fresh Approach to Data Base Management Systems. Part I: Concepts, Considerations and Justifications
This paper is in two parts. In this part, some of the concepts and considerations in the design of a data base management system are set forth, together with justifications for some of the decisions… Expand
