Hi,
I'm doing a DWH for retailers.
i have rep. Type and status in my product dimension, which is rapidly changing. by any chance may i include that in my fact table. so that every time i don't have to go to product table to pull the information. in many of my reports i filter records through rep.type and status.
Thanks,
Regards

I would say it really depends on how large your product table is compared to your fact tables. If you're going to be adding 2 columns, one of which sounds narrow (status) the other wide (type), to a table with millions or billions of rows, to save having to access a table with hundreds or thousands, it's probably not a great idea. But why not try it in your development environment and see how it works?
