techniques to populate fact tables in datawarehouse in SSIS

Question

I am new to data ware house and I was wondering what techniques are used to populate fact tables. From what I have read, its best to have a identity key in the fact table that increments by 1. Same goes for the dimensional tables. Just wondering if that was the case then how would you best do that in SSIS?

Answer 1

You can use an int or bigint column in your SQL table with identity(1,1) to create an auto incrementing ID field and you can use google to find all about the different Data Warehouse techniques.

Some big names are Ralph Kimball and Bill Inmon, but there is much more info out there than anyone could reasonably summarise in the Stack Overflow format.
