Question details

Are the following relations in BCNF? 3NF? (if R is not
in BCNF, decompose it to BCNF; if R is not in 3NF, decompose it to
3NF)
 R(X,Y, Z,T,V): XY>Z, Y>T, Z>V
 R(X,Y,Z,T): X>Y, Y>Z, Z>T
 R(A,B,C): AB>C, B>A, C>B
 R(ABCD): BD>C, AB>D, AC>B, BD>A
 R(ABCD): AD>C, CD>B, BD>C
 R(ABCD): A>C, B>A, A>D, AD>C
 R(ABCD): A>D, C>A, D>B, AC>B
 R(XYZT): XYT>Z, ZT>X, XZ>Y, XZ>T
 R(XYZT): XY>Z, XYT>Z, XYZ>T, XZ>T
 R(XYZT): YT>Z, XY>T, XZ>Y, YT>X
 R(XYZT): YZ>X, XT>Z, ZT>Y, YT>Z
