dcterms:description
Extensions of relational databases which aim at utilizing various aspects of similarity and imprecision in data processing are widespread in the literature. A need for development of solid foundations for such extensions, sometimes called similarity-based relational databases, has repeatedly been emphasized by leading database experts. This paper argues that, contrary to what may be perceived from the literature, solid foundations for similarity-based databases can be developed in a conceptually simple way. In this paper, we outline such foundations and develop in detail a part of the the facet related to similarity-based queries and relational algebra. The foundations are close in principle to Codd's foundations for relational databases, yet they account for the main aspects of similarity-based data manipulation.
