Thanks for your help ,but i don't have to make a query against the two fact tables .
in my case i have two fact tables Circuit and Order the relation between them M-M .i want to create an intermediate fact table to capture the changes occurs on those fact tables ,the new fact table will be Circuit-Order which have another dimensions .how can i handle this case????????????

Are you saying rows will be placed in the circuit/order table as the result of updates to either circuit or order? Or are you building circuit/order as an aggregation of the other two facts?

it's an aggregation with the two facts with another dimensionless on it this new fact .

If 2 fact tables are joined together, doesn't that technically change the database from a Star Schema to a snow flake?
