Functional dependencies are determined from the problem domain, but in the case, you must analyze this data to determine the functional dependencies for R(A,B,C,D,E,F,G) 10 10 20 30 40 50 50 60 70 80 90 100 50 25 50 50 50 75 25 25 25 50 50 10 Identify at least five functional dependencies that apply to this set of data. Based on your functional dependencies, use the closure algorithm to determine the primary key(s) a. b. c. Show how to find a BCNF decomposition of R (A.B,C,D,E,F,G)
