Decompose the following relation R(A, B, C, D) with functional dependencies (FD's) C-B A- BD Compute closures for all subsets of R • List all nontrivial FD's and find possible keys. • Identify all BCNF violations. • Þecompose the relations as necessary into collections of relations that are in BCNF. Only first-level decomposition is required.
