This book focuses on some semantic aspects which have not been studied in previous works and extends the EER model with fuzzy capabilities. The exposed model is called FuzzyEER model, and some of the study's extensions are: fuzzy attributes, fuzzy aggregations, and different aspects on specializations, such as fuzzy degrees and fuzzy constraints. All these fuzzy extensions offer greater expressiveness in conceptual design.
