Mapping Fuzzy UML Model into Fuzzy Nested Relational Database Model

摘要

Information in real world application is often vague or ambiguous. Currently, less research has been done in modeling fuzziness in conceptual data model and design of fuzzy databases. In this paper, based on fuzzy set and possibility distribution theory, the fuzzy UML model and the corresponding graphical representations are presented. In particular, we provide the approach to mapping a fuzzy UML model to a fuzzy nested relational database schema.
