Reengineering fuzzy nested relational databases into fuzzy XML model

Abstract

Data interchange on the Web is a common task today and XML has been the de-facto standard of information representation and exchange over the Web. Also information imperfection is inherent in the real-world applications. Fuzzy information has been extensively investigated in the context of database models. Also fuzzy XML modeling recently receives more attention. In order to present fuzzy data from the fuzzy databases with XML, this paper concentrates on fuzzy information modeling in the fuzzy XML model and the fuzzy nested relational database model. The formal approach to mapping a fuzzy nested relational database (FNRDB) schema into a fuzzy DTD model is developed in the paper.
