Abstract
This paper presents a similarity query generator for DBMSs. A user query which turns out to be too restrictive and returns an empty set of rows is relaxed and transformed into a similar one: the resulting set of tuples will resemble, at some degree, the set defined by the original query. The relaxing activity is based on fuzzy logic and the system provides a user interface to express the query, to obtain suggestions on possible search values and to validate, on the basis of semantic integrity rules, the expressed conditions.
