TL;DR
This paper introduces a set-theoretic definition of functional dependencies in relational schemas, proves an equivalence theorem, and develops an algorithm to identify these dependencies, demonstrated through a concrete example.
Contribution
It provides a new set-theoretic framework and an algorithm for determining functional dependencies in relational schemas, enhancing understanding and analysis.
Findings
Set-theoretic definition of functional dependencies
Proved an equivalence theorem for dependencies
Developed an algorithm for dependency search
Abstract
An alternative definition of the concept is given of functional dependence among the attributes of the relational schema in the Relational Model, this definition is obtained in terms of the set theory. For that which a theorem is demonstrated that establishes equivalence and on the basis theorem an algorithm is built for the search of the functional dependences among the attributes. The algorithm is illustrated by a concrete example
