Title

Analysis of tradeoff between data accuracy and performance of databases

Source

Information systems. 21(1996) no.8, S.653-672

Year

Abstract

Proposes a model for estimating the accuracy of a database and for the planning of computing resources based on database performance and accuracy requirements of various groups of users. Focuses on data items which are derived from numeric domains where some quantitative statements can be made about the deviation of the stored value in the database from their current real values. Describes the computational procedure incorporating the computing system environment model that has been developed, and discusses its applicability to a realistic scenario with numerical results. Discusses conclusions and future extensions to the research
