A case table is the one which should contain all the cases necessary for your predictions. So for example you have a scenario in which you want to predict the probability of customers who have bought your product say, a Nokia handset. Now there are lot of assumptions you will be requiring such as gender,income,age etc. And the table which will contain this values are generally used for case table.
A nested table is represented in the case table as a special column that has a data type of TABLE. For any particular case row, this kind of column contains selected rows from the child table that pertain to the parent table.
