1. Decomposition Assume R = (S T U V W X Y Z) and F = {S TV , T U, W XY , SW Z} Where S, T, U, V , W, X, Y and Z represent individual attributes. Decompose R into BCNF, lossless, dependency preserving. If this is not possible, decompose R into 3NF, lossless, dependency preserving. Show your decomposition and state whether is it BCNF or 3NF.

2. Decomposition Assume R = (S T U V W X Y Z) and F = {S TUV W, T UV , W XY , V Z }. Where S T, U, V , W, X, Y and Z represent individual attributes. Decompose R into BCNF, lossless, dependency preserving. If this is not possible, decompose R into 3NF, lossless, dependency preserving. Show your decomposition and state whether it is BCNF or 3NF.
