Question
What is TRUE about the Third Normal Form (3NF)?a.All of the answerb.Data duplication is reduced by using 3NFc.When a relation is in 2NF and does not contain transitive partial dependencies, it will be in 3NFd.It helps maintain the integrity of the data
Solution
The statement "All of the answer" is TRUE about the Third Normal Form (3NF).
Here's why:
a) All of the answer: This is true because all the following options are correct about 3NF.
b) Data duplication is reduced by using 3NF: This is true. The Third Normal Form (3NF) is a normalization process used to reduce the duplication of data and ensure referential integrity by ensuring that the entity is in second normal form (2NF) and all the attributes in a table are determined only by the candidate keys of that table.
c) When a relation is in 2NF and does not contain transitive partial dependencies, it will be in 3NF: This is also true. A database table is in 3NF if it is in 2NF and there are no transitive functional dependencies of non-prime attributes on the primary key.
d) It helps maintain the integrity of the data: This is true as well. By eliminating or reducing redundancy and ensuring data dependencies make sense, 3NF helps maintain the integrity of the data.
