Given the function and functional dependencies. Find the candidate keys, primes and find the violations for the following forms 1NF, 2NF, 3NF and BCNF; including the revised tables.

parasites(l,a,w,y,e,r,s)

aw ---> y,e,s

a ---> e

s ---> w

l ---> r

Given the function and functional dependencies. Find the candidate keys, primes (attributes of the candidate key which define the uniqueness E.g SSN in an employee database) in the follwoing forms, 1NF, 2NF, 3NF and BCNF.

This problem is diffciult because the letters that comprise the attributes of the table, parasite provide no insight into which would be candidate keys. My Professor says that all the info I need is in the above functional dependencies. Help would be appreciated!
