Question
Choose the correct answerWhich forms simplifies and ensures that there are minimal data aggregates and repetitive groups:Options1NF3NFNone of theseAll of these2NF
Solution
The correct answer is 3NF (Third Normal Form).
Here's why:
1NF (First Normal Form) only eliminates duplicate columns from the same table and creates separate tables for each group of related data.
2NF (Second Normal Form) removes subsets of data that apply to multiple rows of a table and place them in separate tables.
3NF (Third Normal Form) goes a step further. It simplifies and ensures that there are minimal data aggregates and repetitive groups. It removes columns that are not dependent upon the primary key.
So, 3NF is the form that simplifies and ensures that there are minimal data aggregates and repetitive groups.
