Question: Let R be a relation with attributes ABCDEG and (i) (1 point) Find all the keys of R. (ii) (4 points) Find a BCNF decomposition

Let R be a relation with attributes ABCDEG and (i) (1 point) Find all the keys of R. (ii) (4 points) Find a BCNF decomposition of R with lossless join () (2 points) Is the decomposition obtained in (ii) dependency pre (iv) (5 points) Find a 3NF decomposition of R with lossless join and with respect to F. (Show how the decomposition is obtained.) serving with respect to F ? dependency preserving with respect to F (show the steps). Is the obtained in (i) dependen decomposition also in BCNF
