Question 1: Normalization
Consider a relation X with six attributes WYSMFE where WS is a composite primary key for X.
Assume X has the following functional dependencies (X is one table with the attributes W, Y, S,
М, F, E):
1.1)
WS > YMFE
S> YΜΕ
E > M
a) In what normal form is relation X? Explain why?
b) Is it possible to decompose X into a number of relations in order to achieve a higher normal
form? Explain how (this means using English sentences and a diagram showing the final
relation(s)).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4f19521b-984a-46ea-87dd-80ca1e198282%2Ff6c84c6a-8622-4aa3-8751-75c7fd179ff3%2Fpib7fb_processed.png&w=3840&q=75)
