Solution

The form that simplifies and ensures that there are minimal data aggregates and repetitive groups is 3NF (Third Normal Form).

Here's why:

  1. First Normal Form (1NF): This form eliminates duplicate columns from the same table and creates separate tables for each group of related data.

  2. Second Normal Form (2NF): This form removes subsets of data that apply to multiple rows of a table and places them in separate tables.

  3. Third Normal Form (3NF): This form goes a step further and removes columns that are not dependent upon the primary key. This is the form that ensures minimal data aggregates and repetitive groups.

So, the answer is 3NF.
