2. Consider the relational schema R with key (a,b,c) and no alternative keys. Below all its full functional dependencies are listed. R(a, b, c, d, e, f, g, h) {a,c} +e {a,b} d b + {g, h} {a,b,c} + f 9 +h (a) Explain in which normal form the schema is. [3 marks] (b) Normalise schema R above to 3rd Normal Form. Make sure you declare primary and foreign keys correctly whenever you intro- duce a new schema. Also state explicitly which schema(s) are intermediate and which are part of the result. [8 marks]
