Non trivial Functional Dependency and Trivial Functional Dependency HD

Non trivial & Trivial Functional Dependency DBMS Databases Video lecture for gate exam preparation iit Hindi, Trivial functional dependency vs. non-trivial functional dependency Trivial − If a functional dependency (FD) X → Y holds, where Y is a subset of X, then it is called a trivial FD. Trivial FDs always hold. Non-trivial − If an FD X → Y holds, where Y is not a subset of X, then it is called a non-trivial FD. trivial functional dependency definition non trivial functional dependency nontrivial functional dependencies non trivial functional dependency example trivial and non trivial functional dependency in dbms trivial functional dependency in dbms with example bcnf multivalued dependency non trivial functional dependency example difference between trivial and non trivial dependencies trivial and non trivial functional dependency in dbms bcnf functional dependency database what is full functional dependency define functional dependency in dbms functional dependencies examples find out non trivial functional dependency in a following table?
