چکیده

A major bottleneck in implementing sampling as a primitive relational operation is the inefficiency of sampling the output of a query. We highlight the primary difficulties, summarize the results of some recent work in this area, and indicate directions for future work.

Max-Min averaging operator: fuzzy inequality systems and resolution

 Minimum and maximum operators are two well-known t-norm and s-norm used frequently in fuzzy systems. In this paper, two different types of fuzzy inequalities are simultaneously studied where the convex combination of minimum and maximum operators is applied as the fuzzy relational composition. Some basic properties and theoretical aspects of the problem are derived and four necessary and suffi...

A Sampling Algebra for Aggregate Estimation

As of 2005, sampling has been incorporated in all major database systems. While efficient sampling techniques are realizable, determining the accuracy of an estimate obtained from the sample is still an unresolved problem. In this paper, we present a theoretical framework that allows an elegant treatment of the problem. We base our work on generalized uniform sampling (GUS), a class of sampling...

A Treatment of Correlated Attribute Uncertainty in Array Database Systems

The purpose of this document is to summarize ongoing research into handling uncertainty in database systems, and present my contributions to that research. Uncertainty presents a particular problem for databases because the relational model leaves no room for ambiguity in database fields. Traditional database operators such as selection and join operate on constant values as opposed to probabil...
