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, M, F, E): WS è YMFE S è YME E è M   In what normal form is relation X? Explain why?   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)).   officeNo officeAddress telNo mgrStaffNo name B001 8 Jefferson Way, Portland, ME 97201 503-555-3618 S1500 Tom Daniels B002 City Center Plaza, Seattle, WA 98122 206-555-6756 S0010 Mary Martinez B003 14 – 8th Avenue, New York, NY 10012 212-371-3000 S0145 Art Peters B004 16 – 14th Avenue, Seattle, WA 98128 206-555-3131 S2250 Sally Stern   Primary key: officeNo   Why the above table is not in 3NF?
