Hi, what is the minimal cover for this relation schema? TD -> O #redundant as FD TDN -> Pl will also give O (?) OD -> T #redundant (?) TPl -> N #redundant as FD DTOPl -> Po will also give N (?) TDN -> P DTOP -> X

Consider the relation schema R = (N, Y, P, M, C) and assume that the following set of functional dependencies holds on R: F = { N → M, NY → P, M → C} The letters can be interpreted as follows: R = (Model_Number, Year, Price, Manufacturing_Plant, Color). Give a lossless-join decomposition of R into Boyce-Codd normal form. Make sure to use the algorithm and to show all details. Does your decomposition preserve functional dependencies? Justify your answer. Is R in 3NF? Justify your answer. You can use the fact that R has only one candidate key, NY.
