2NF PK

Functional Dependencies in EMPLOYEE2 EmpIDCourseTitleDateCompletedSalaryDeptNameName Dependency on entire primary key Dependency on only part of the key Define functional dependencies of above table using a functional dependency notation, then normalize to 2NF PK

2NF Rental Info TransID VideoID Copy# Title Rent Depends only on VideoID Depends on both TransID and VideoID Below table name is “Rental Info”. Arrowed direction shows functional dependency information. 1.Define functional dependencies of table using functional dependency notation then normalize to 2NF PK

3NF: Define functional dependencies of below table using a functional dependency notation, then normalize to 3NF PK
