Answer / Alka
Non-Additive Facts refer to measures that don't follow the additive property (i.e., if you sum up the values, they do not equal the total). Examples of non-additive facts include rankings, counts with duplicates, and ratios. They are challenging to analyze using traditional OLAP techniques because they require more complex calculations and don't support aggregations like sum or count.
