Hi,
I am in the process of designing the data warehouse. My Question is can I define the relationship between dimension tables. Like I have country,customer and time zone dimension tables. Can I add relationship between customer,country and time zone just to validate the data before load whether the country and zip code is correct or should I integrate the country and time zone with customer itself. If I integrate this. Is it going to affect the performance. 'cos for every record it is going to validate all these things before load.
Can I create sequences for primary keys(fact tables and for some of the dimenasion tables also). Is it OK to have a sequence as primary key.
I need your expert views on this.
Regards,
