Abstract

This paper is mainly concerned with the extension of database management systems querying capabilities, so that users may address queries involving preferences and get discriminated answers. The use of flexible predicates and linguistic quantifiers interpreted in the framework of the fuzzy set theory is advocated for defining a query language, called SQLf. This language extents the functionalities offered by SQL and it is considered here from a query processing point of view. We concentrate this work in the fuzzy quantified SQLf queries semantic and evaluation mechanism.
