A functional dependency (FD) is a relationship between two attributes, typically between the PK and other non-key attributes within a table.For any relation R, attribute Y is functionally dependent on attribute X (usually the PK), if for every valid instance of X, that value of X uniquely determines the value of Y. http://www.facweb.iitkgp.ac.in/~shamik/spring2024/dbms/dbms2024.html 3 us states with spanish names Webonly Armstrong’s axioms.

Note: In case of lossless decomposition, if the following equation is not satisfied, then it is said to be ‘lossy-decomposition’. πR1 (r ) X πR2 (r) = r .
