Fuzzy preference queries to relational databases. (English) Zbl 1246.68011

London: Imperial College Press (ISBN 978-1-84816-869-5/hbk; 978-1-84816-870-1/ebook). xvi, 330 p. (2012).
The manipulation of databases is an integral part of a pervasively information-focused modern world. This book puts forward to a suggestion to advocate preference queries and fuzzy sets as a central concern in database queries and offers an important contribution to the design of intelligent information systems. Preference queries provide a basis for rank-ordering of the items retrieved.
This book aims to show that fuzzy set theory constitutes a highly expressive framework for modeling preference queries. It presents a study of the algorithmic aspects related to the evaluation of such queries in order to demonstrate that this framework offers a good trade-off between expressivity and efficiency. The presentation is self-contained, and numerous examples and proofs are included.
