Abstract
Fuzzy databases manage imprecision in its schema and offer tools for flexible querying. A true standard does not exist. Relational databases are usually the base for the implementation of fuzzy databases. In this paper we propose a general model to represent and querying fuzzy types in any relational database. The model is implemented within the Hibernate Framework.
