Fuzziness in databases is used to denote uncertain or incomplete data. Relational databases stress on the nature of the data to be certain. This certainty based data is used as the basis of the normalization approach designed for traditional relational databases. But real world data may not always be certain, thereby making it necessary to design an approach for normalization that deals with fuzzy data. This paper focuses on the approach for designing the Fifth Normal Form (5NF) based on join dependencies for fuzzy data.
