(a) Show that R is not in BCNF using the functional dependency A → BCD. (b) Show that AG is a superkey for R (c) Compute a canonical cover Fc for the set of functional dependencies F. Show your work. (d) Give a 3NF decomposition of R based on the canonical cover found in (c). Show your work. (e) Give a BCNF decomposition of R using F. Show your work.arrow_forwardThe following entity-relationship (ER) diagram models a database that helps car deal- ers maintain records of customers and cars in their inventory. Construct a relational database schema from the ER diagram. Your set of schemas should include primary-key and foreign-key constraints and you should ensure there are no redundant schemas. has_model model modelID name vehicle has_vehicle VIN dealer_ID brand name has_available_option has_option has_dealer options options_ID specification dealer dealer ID name customer_ID owned_by customer customer ID namearrow_forward
