Use the schema R in the following questions:
R = (ABCDEFGH, {BE ? GH, G ? FA, D ? C, F ? B})(a) What is a key of R? (b) What is the attribute closure of GH ? (c) Can there be a key that does not contain D? If such a key exists, give it; otherwise explain why it is not possible. (d) Is the schema in BCNF? Give the reason for your answer. (e) Use one cycle of the BCNF synthesis algorithm to decompose R into two sub-relations. For each sub-relation, explain whether or not it is in BCNF. (f) Give the general condition that guarantees that a decomposition is lossless. Apply the condition to your decomposition to show whether or not it is lossless. (g) Give the general condition that guarantees that a decomposition is dependency preserv- ing. Apply the condition to your decomposition to show whether or not it is dependency preserving. (h) * Consider a schema (R, ), where R is a set of attributes and is a set of functional dependencies. Assume further that
