Abstract
Processing slowly changing dimensions (SCDs) is a common ETL operation when you are dealing with data warehouses. The SSIS data flow has a SCD transform, which provides a wizard that outputs a set of transforms you need to handle the multiple steps of processing SCDs. Although the built-in SCD transform can be useful, it is not ideal for all data loading scenarios. This chapter describes how to make the most of the SCD transform and provides a couple of alternative patterns you can use.
