Question
Which forms simplifies and ensures that there are minimal data aggregates and repetitive groups:
Options
- All of these
- 2NF
- 1NF
- 3NF
- None of these
Solution
The form that simplifies and ensures that there are minimal data aggregates and repetitive groups is 3NF (Third Normal Form).
Here's why:
-
First Normal Form (1NF): This form eliminates duplicate columns from the same table and creates separate tables for each group of related data.
-
Second Normal Form (2NF): This form removes subsets of data that apply to multiple rows of a table and places them in separate tables.
-
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.
