Consider a relation schema R(a,b,c,d,e) and a set of functional dependencies F={abc,dec,bd}. a) Is R in BCNF? If not, list all the functional dependencies in F that violate BCNF and explain why they are violations of BCNF. b) Use the BCNF decomposition algorithm to decompose R, as necessary, into a collection of relation schemas that are in BCNF. Explain your steps
