Description
| - We present logical foundations for an extension of Codd's relational model of data which aims at utilizing various aspects of similarity. This paper argues that solid foundations for similarity-based databases can be developed in a conceptually sound way. We outline the foundations and propose two query systems for similarity-based databases: a domain relational calculus (DRC) and a relational algebra (RA). We compare the expressive power of DRC and RA in our model and prove relational completeness of RA over DRC. A major implication of the paper is that similarity-based data querying can be made an integral part of an extended, similarity-based, relational model of data which is based on first-order predicate logics using residuated structures of truth values in much the same way as the querying in the Codd's model is based on the classic first-order predicate logic.
