contract multi-value or multi-fact or ...

Post  elementary on Wed Feb 06, 2013 12:01 pm

I want to track contracts on a monthly basis. A contract is defined per customer.
- A contract can contain 1 or more modules.
- A contract can contain 1 or more interfaces.
- A contract can contain 1 or more suppliers.
- A contract can contain 1 or more ....

I want to know on a re-current basis which modules a certain customer has
I want to know the customer which have a certain module and have a certain interface currently
I want to know the customer which have a certain module and have a certain interface in a certain month
...

Any idea on how to model this? My initial approach is to have 1 fact for customer-month-modules, 1 fact for customer-month-interfaces, etc.

Any help appreciated!

cheers!

Things you count or sum are facts. Things you filter by are dimensions.

I want to know the customer (filter) which have a certain module (fact) and have a certain interface (dimension) currently. Or it just may be a factless fact table where all three of these things are dimensions and their intersection is the fact.
