Handling Advanced Data Warehouse Scenarios in SSIS
Do you have complex dimensions in your data warehouse? Parent-child, late arriving, type 3 or type 6? In this session, we'll cover some SSIS patterns for handling each of these, along with tips for making them perform well.
So you’ve used SSIS to populate a simple star schema data mart, and everybody’s happy. But now you have new requirements that require more advanced data warehouse approaches, like late arriving dimensions, parent child dimensions, and Type 3 or Type 6 slowly changing dimensions (SCD). How do you handle those in a scalable, efficient way in SSIS? This session will present some common patterns for handling these scenarios. You’ll learn when to use each advanced approach and the pros and cons associated with each pattern. You will learn how to implement these patterns in SSIS, and how to tune them for high performance.
