Step 1
Given the functional dependencies BCE, EDA, and AB, we can see that the left side of each functional dependency is not a superkey. To check if the left side of each functional dependency is a superkey, we need to find the closure of each attribute set. Closure Show more…

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.

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

Normalization
Consider the relation schema R = (N, Y, P, M, C) and assume that the following set of functional dependencies holds on R: F = { N → M, NY → P, M → C} The letters can be interpreted as follows: R = (Model_Number, Year, Price, Manufacturing_Plant, Color). Give a lossless-join decomposition of R into Boyce-Codd normal form. Make sure to use the algorithm and to show all details. Does your decomposition preserve functional dependencies? Justify your answer. Is R in 3NF? Justify your answer. You can use the fact that R has only one candidate key, NY.
