Final answer:
The conditions that violate 3NF occur when a non-key attribute determines another non-key attribute and when a proper subset of a key determines a non-prime attribute, which corresponds to option B) Non-key, Non-key, Attributes.
Step-by-step explanation:
The question is related to database normalization, specifically the third normal form (3NF), which is a concept in the field of relational database design. Conditions that violate 3NF are when
A non-key attribute determines another non-key attribute
A proper subset of a key of R determines a non-prime attribute
From the options provided, the correct answer is:
A) Key, Attribute, Functions
B) Non-key, Non-key, Attributes
C) Prime attribute, Non-prime attribute, Implies
D) Attribute, Key, Relate
Therefore, the correct fill-in-the-blank statement to describe a situation that violates 3NF in a database is 'A non-key attribute determines another non-key attribute' and 'A proper subset of a key of R determines a non-prime attribute'. This corresponds to answer choice B).
