CUSTOMER(cust Phone, name, preferences) KTV STUDIO(studioName, location, equipment List, rateType) BOOKING (cust Phone, studioName, statDateTime, duration, specialRequest) RATE(rateType,unt Price) (i) Find all functional and multivalued dependencies in the relational schemas CUSTOMER, KTVSTUDIO, BOOKING, and RATE. (ii) Find all minimal keys in the relational schemas CUSTOMER, KTVSTUDIO, BOOKING, and RATE. List the derivations of all minimal keys. (iii) (iv) For each one of the relational schemas find the highest normal form a schema is in. List the justifications for each highest normal form found. Decompose all relational schemas that are not in 4nF into 4NF. List all relational schemas obtained from the decompositions. Remember to indicate the primary key and foreign keys (if any).
