You manage a SQL Server 2008 Analysis Services (SSAS) data warehouse for a school district. All tests are administered via a third-party application. Results are collected in your SSAS data warehouse and moved to a Scores fact table for analysis. This warehouse also includes a Student Dimension which contains attributes related to each student. The school year is starting, and the district administration wants the Student Dimension updated hourly so that new students can be identified and tracked. However, test scores located in the Scores fact table should not be updated as part of this incremental processing strategy. You need to implement this functionality. Which option should you use?
