prime attributes are the attributes of a candidate key which will give uniqueness.
a candidate key is (the subset of superkey) which gives uniqueness.
Super key is the maximum set of attributes that can provide uniqueness
example
ABCDE is a super key
AB CD DE are the candidate keys s.t. AB is the primary key. CD and DE are the secondary/alternate keys.

A relation violates third normal form (3NF) if it has a transitive dependency where a non-prime attribute depends on another non-prime attribute (which itself is not a candidate key). This means that a non-prime attribute is functionally dependent on another non-prime attribute rather than on a candidate key.

Describe the purpose of normalizing data and also list out the dependencies involved in the process of normalization?

What is the more common name for attribute?
In a database management system (DBMS), an attribute may describe a component of the database, such as a table or a field, or may be used itself as another term for a field.
