(i) Find all the minimal super keys of the relational table 𝑅. List the derivations
of all minimal keys.
(ii) Identify the highest normal form of the relational R. Remember that the identification of a normal form requires analysis of the valid functional dependencies.
(iii) Decompose the relational table R into a minimal number of normalized relational tables in BCNF. Remember to indicate the primary key and
