A Methodology of Integrating Fuzzy Relational Databases in a Multidatabase System

Although significant progress has been made in developing multidatabase systems that integrate component databases containing crisp data, little has been reported on integmtingfuzzy databases in such systems. In this paper, we investigate the problem of integrating fuzzy relational databases in a multidatabase system. We identify new types of conflicts that may occur in schemas and data due to the inclusion of fuzzy relational databases. We propose a methodology that resolves these new types of conflicts in a procedural manner. In addition, the methodology puts the resolution of these new conflicts into the context of the resolution of other types of conflicts. A fuzzy-probabilistic data model is used to facilitate the integmtion.
