those things we can identify from ur data model table,those are created automatically based on ur data source (information density) &how u define ur keys(subset ration).

How do we test the datamodel with help of subset ratio and information density.---there is no way to test,but u can find how much correctly u define ur keys (but it not always right,means don't expect 100% ratio as correct) from data model by looking those percentages.
