(1) Consider the following relational schema and a set of functional dependencies valid in the schema. R (A, B, C, D, E) Find the highest normal form the relational schema is in. If the schema is not in BCNF the decompose the schema in to the smallest number of relational schemas each one in BCNF. Provide a complete justification of your answer (2) Consider the following relational schema and a set of functional dependencies valid in the schema.
