With type 2 dimensions, I will have to go and update dim keys in fact tables, which will be little messy. For ex., I have product dimension with fields say prdid, prdname, effectivefromdate and effectivetodate. I have salesfact where I have prdid, saledate and salesvolume.

I am designing a data model where data ( both dimension and fact) will have back in time changes or retroactive changes. Please suggest me pointers on how to handle it.
