This paper presents an easy-to-use and easy-to-implement framework for fuzzy data classification and extraction in relational databases. The main benefits of the framework are: (i) a fuzzy data classification model for relational databases; (ii) flexible membership function configuration; (iii) automatic membership degree computation; (iv) a fuzzy data retrieval mechanism fully supported in SQL queries. In order to validate the proposed framework, a case study is implemented in a social welfare system using RDBMS Oracle 11g and PL/SQL programming language.
