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> ΥΜΕ E > M a) In what normal form is relation X? Explain why?

**ICS 311 - Database Management Systems** **Assignment 5** *Due: See Syllabus* **Question 1: Normalization** Consider a relation X with six attributes WYSWFE 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, M, F, E): 1.1) - WS ➔ YMFE - S ➔ YME - 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)).
