Homework #4: Normalization
1. Consider the following relation that involves student data:

Assume that only one professor teaches a class section, and professors teach in only one department. Suppose the following dependencies exist:

What normal form is the relation in? Normalize it up to 3NF.
2. Given the EMPLOYEES relation below:
Emp_no Ename Lcode Lstatus
25 Clay NJ5101 1
23 Thaisz NJ5101 1
38 Good FL6321 4
17 Baid NY2091 3
57 Brown NY2092 3
The relation schema for the above relation is EMPLOYEES, where
Emp_no: employee number
Ename: employee name
Lcode: location code
Lstatus: location status, each location has a status code
What normal form is the relation in? What are the dependencies? Normalize it up to
3NF.
