Slowly changing dimensions- an integrated approach

There are many treatments of table design for slowly changing dimensions, and almost as many on doing ETL on an SCD. Much less has been said about building a cube around a slowly changing dimension.
In this session, Mark will review the types of slowly changing dimensions, describe the performance implications of various methods of loading SCDs in SSIS (SCD task, Lookups, Merge, and Script component), and build a unique way of using the versions in Analysis Services
Presented by Mark Stacey at SQLBits XI
