Explain how to apply 1NF criteria to the Parent relation shown in the below table. Show the table with the 1NF criteria.
ID | name | children | birth_date |
---|---|---|---|
1001 | John Doe | Betty, Frank | 2-2-88, 4-3-90 |
1002 | Jane Doe | Betty, Frank | 2-2-88, 4-3-90 |

Note: The rules for 1NF are straightforward. A relation is said to be in first normal form if the data is held in a two-dimensional table with each attribute represented by an atomic value. In other words, the intersection of a row and a column must contain an indivisible value. To illustrate the normalization process, a new relation will be introduced.
