Q1 (Grade: 8 marks). Suppose we have a relation R with attributes ABCD. Answer the following: 1- Assume that the functional dependency BCD holds in R. Propose the value of attributes ( B and C ) to break FD (i.e., not satisfy BCD ). 2- Are the sets ABC and AC,BC equivalent? If yes, explain why. If no propose a value of attributes (A,B) of R that satisfies ABC and AC but does not satisfy BC. 3- Are the sets ABC and AB,AC equivalent? If yes, explain why. If no, propose a value of attributes (A,B) of R that satisfies ABC but not AB and AC. Q2 (Grade: 7 marks). Suppose the final ER diagram is shown below. Construct tables (schema) from ERD with their relational connection. Q3 (Grade: 10 marks). UPS, a global shipping and logistics solutions company, sends up-to-date information on each shipped item's processing and location (tracking items). To do this, UPS relies on a company-wide information system. - Shipped items can be characterized by item number (unique), weight, dimensions, insurance amount, destination, and final delivery date. - Shipped items are received into the UPS system at a single retail center. - Retail centers are characterized by their type, uniquelD, and address. - Shipped items arrive at their destination via one or more standard UPS transportation events (i.e., flights, truck deliveries). These transportation events are characterized by a unique scheduleNumber, a type (e.g., flight, truck), and a deliveryRoute
