A new definition of fuzzy functional dependency in fuzzy relational databases

  title={A new definition of fuzzy functional dependency in fuzzy relational databases},
  author={Juan C. Cubero and M. Amparo Vila},
  journal={Int. J. Intell. Syst.},
The need to incorporate and treat information given in fuzzy terms in Relational Databases has concentrated a great eeort in the last years. This paper focuses on the treatment of functional dependencies (f.d.) between attributes of a relation scheme. We review other approaches to this problem and present some of its missfunctions concerning intuitive properties a fuzzy extension of f.d. should verify. Then we introduce a fuzzy extension of this concept to overcome the previous anomalous… CONTINUE READING
