Some approaches for relational databases flexible querying

  title={Some approaches for relational databases flexible querying},
  author={Patrick Bosc and Olivier Pivert},
  journal={Journal of Intelligent Information Systems},
One of the main objectives of third generation databases is to design database management systems which provide users with more and more functionalities. In such a wide context, various proposals have been made in order to introduce some kind of explicit or implicit flexibility into user queries. In this paper, we propose a classification of the various approaches dealing with imprecise queries. Moreover, we show that the approach based on fuzzy sets is powerful enough to answer a wide range of… CONTINUE READING
