Consider the relation R(A,B,C,D) with FDs A -> B, C -> D, AD -> C, BC -> A. Check for both BCNF and 3NF status. Which of the following is the most accurate summary of the results?
Consider the relation R(A,B,C,D) with FDs A -> B, C -> D, AD -> C, BC -> A. Check for both BCNF and 3NF status. Which of the following is the most accurate summary of the results?R is in BCNF and 3NF. No normalization is necessary.R is in 3NF but not in BCNF. We should try normalizing to BCNF, but this results in information being lost. As such, we stay with the original schema.R is in BCNF but not in 3NF....

5c. Consider the relation R(ABCDE) with the set of functional dependencies F={BE→D, DE→A, AD→C, B→E}. Using decomposition, find a lossless, dependency preserving, BCNF set of relations for R, if such exists. Be sure to identify the projections of the functional dependencies onto the resulting relations at each stage of the decomposition.
