14.25. Consider the universal relation R(A, B, C, D, E) and the set of functional dependencies A -> B C, C D -> E, B -> D, E -> A List the candidate keys for R ? Decompose R into 2 NF and 3 NF relations.

Step 1
Step 1: To find the candidate keys for R, we can start by using the closure of each attribute to determine which combinations of attributes form superkeys. Show more…

Consider the given relation and functional dependencies $R(A B C)$ $F D=(A B \rightarrow C$ $C \rightarrow A)$ The relation is in which normal form? (A) $1 \mathrm{NF}$ (B) $2 \mathrm{NF}$ (C) $3 \mathrm{NF}$ (D) BCNF

Consider the relation schema R = (A, B, C, D, E, F, G, H, I, J) with functional dependencies FD = {B→E, E→FH, BCD→G, CD→A, A→J, I→BCDE, H→I}. Determine if B→J holds and list every candidate key. Show each step. THEN Consider a relation schema R(X, Y, Z) with the functional dependencies XY→Z and Z→X. Can we conclude that Y→XZ holds? If yes, please argue why. If no, please argue why not by giving a counterexample.

Given relation R(A, B, C, D, E, F, G) and the set of functional dependencies F = {BCD → A, BC → E, A → F, F → G, C → D, A → G}, decompose R into 3NF. Show your steps. Is this decomposition also BCNF? Why or why not? Note: This requires you to first determine the key(s) of R.
