A database is in third normal form if it is second normal form and:
a. It contains no data redundancies
b. It contains no foreign keys
c. It contains no transitive dependencies
d. All of these
Homework Answers
Solution: It contains no transitive dependencies
Explanation: For conversion from 2NF to 3NF, create new tables for the elimination of transitive dependencies, thus no transitive dependencies and reassignment of the corresponding dependent attributes

To be in the third normal form,
Hint: In order to in 3NF you must first have attained 1NF and
2NF so all of the above is the correct answer. In the database
design world the saying is that to be completely normalized the
data be represented "by the key, the whole key, and nothing but the
key so help me Codd". Ted Codd was the person behind the
development of the relational theory back in the 1960s and 70s....
