Question
Choose the correct answerWhich forms simplifies and ensures that there are minimal data aggregates and repetitive groups:Options3NF2NFNone of these1NFAll of these
Solution
The correct answer is 3NF (Third Normal Form).
Here's why:
1NF (First Normal Form) deals with atomicity. It ensures that each cell in a table has only unique and atomic (indivisible) values.
2NF (Second Normal Form) deals with the concept of full functional dependency. It ensures that each non-key attribute is fully functionally dependent on the primary key.
3NF (Third Normal Form) goes a step further. It ensures that there are no transitive functional dependencies in the table, which simplifies the data and ensures that there are minimal data aggregates and repetitive groups.
So, 3NF is the form that simplifies and ensures that there are minimal data aggregates and repetitive groups.
