Consider a relation R=(A, B, C, D, E, F, G, H, I, J) and the set of functional dependencies F = {{AB→C}, {A→DE}, {B→F}, {F→GH}, {D→IJ}}. (a) (b) (c) What is the key for R? Decompose R into 2NF. Based on your answer of 2NF in (b), Decompose R into 3NF relations.
All parts of this question use the relation R = (ABCDEG) with the set of functional dependencies F = {A→BC, AD→G, C→D, G→C, BC→BDEG}. Use 3NF synthesis to find a 3NF decomposition of R that is both lossless-join and dependency-preserving. You must show all FDs that hold on each resulting relation. As a final step, minimize the number of relations in your decomposition, while still ensuring that each relation is in 3NF. 2.Give an example of a query that would run more slowly in your decomposition from above than in the original relation R. You must explain your answer.
