   I would doubt that you would need FKs since you've already validated your data. FKs are most valuable when you are trying to protect the data from many users or programs, and not all may enforce relational integrity.

Hi.

I have an operational database with primary and foreign keys and we are now building a set of aggregates (daily, monthly etc) to speed up the reporting. Do I need to replicate the same foreign keys
on the aggregates that we have on the base tables? I'm thining no because there will be no new FKs added to the aggregates and all the existing values will have been validated via the FKs existing on the base tables. Is my reasoning correct? Am I missing something?

thank you

Gene
