    Hello Santosh,

    Some points from my side:

    1. While creating table, ROW Store, Column Store and Table type are the option.

    For modelling the table should be Column Store type.

    For more explanation please find the below link:

    Table types are used to define parameters for a procedure.

    2. Please find the link below for difference between Inner and referential join.

    Hope it is useful for you.

      Hello Neha,

      Does it mean, if i have any filter on my right table, then referential join doesn't work so it will fetch "0" records? is it?

      Can you be more clear on this line?

    referential joins are to ensure the data integrity during insertion of data. if we have a referential join between dimension table customer and fact table sales on customer id field, then this means, we cannot insert any record with customer id that is not in customer table. these constraints help to maintain the data integrity.
