Functional dependencies of data tables over domains with similarity relations
Original language description
We study attribute dependencies in a setting of fuzzy logic. Our dependencies are described by formulas $ARightarrow B$ where $A$ and $B$ are fuzzy sets of attributes. The meaning of $ARightarrow B$ is that any two objects that have similar values on attributes from $A$ have also similar values on attributes from $B$. Our approach generalizes classical functional dependencies from databases and also several approaches to functional dependencies in fuzzy databases. We show a connection to other interpretation of formulas $ARightarrow B$ which we studied before. Although the two interpretations are different, they have the same concept of semantic entailment. This connection enables us to find a complete axiomatization of reasoning with our attributedependencies. We prove completeness theorem in the usual as well as in a so-called graded style. The connection also enables us to compute a complete non-redundant basis of all functional dependencies which are true in a data table. We pr
