WebIt is a normalization level in DBMS. A relation is said to be in 3rd normal form in DBMS (or 3NF) when it is in the second normal form, but no transitive dependency exists for a non-prime attribute.

This includes creating tables and establishing … WebSecond Normal Form (2NF) In the 2NF, relational must be in 1NF. In the second normal form, all non-key attributes are fully functional dependent on the primary key. Example: Let's assume, a school can store the data of teachers and the subjects they teach. In a school, a teacher can teach more than one subject. TEACHER table. TEACHER_ID.
WebSecond Normal Form (2NF) The normalization of 1NF relations to 2NF involves the elimination of partial dependencies. A partial dependency in DBMS exists when any non-prime attributes, i.e., an attribute not a part of the candidate key, is not fully functionally dependent on one of the candidate keys..
