- 2 2 Points Prove Or Disprove The Following Statement It Is Possible For A Set Of Mvds To Imply A Non Trivial Fd Mor 1 (55.14 KiB) Viewed 22 times
2. (2 points) Prove or disprove the following statement: it is possible for a set of MVDs to imply a non-trivial FD. More precisely, there exists a set A of MVDs and a non-trivial FD f such that A Ff. (An FD is trivial if it is of the form X + Y where Y CX; such an FD is always true.). Provide a direct proof, without using the soundness and completeness of the axioms for FDs and MVDs.
