The model is called model FuzzyEER affected, and some extensions being studied are: fuzzy attributes, fuzzy aggregations and different aspects on specializations, such as fuzzy degrees, fuzzy constraints, etc. Fuzzy Databases: Modeling, Design and Implementation also proposes a method to translate the model into DBMS FuzzyEER classical, and defines FSQL (Fuzzy SQL), an extension of the SQL language that allows users to write flexible conditions in queries, using all extensions defined by the model FuzzyEER.
