I have seen the tip Dynamically Control Data Filtering in SQL Server Reporting Services Reports which showed how to leverage a SQL Server database table to filter sales data based on the user running the report. I have a similar requirement to implement dynamic filtering except my data is in a SQL Server Analysis Services (SSAS) cube and the users query the data with a variety of different tools. How can I implement dynamic security in my case?

Change data capture is a new feature in SQL Server 2008 that provides an easy way to capture changes to data in a set of database tables so these changes can be transferred to a second system like a data warehouse. This document provides guidance on how to configure change data capture parameters to maximize data capture performance while minimizing the performance impact on the production workload. The scope of this document is limited to the capture of change data and the cleanup process. Querying the changed data is out of scope for this white paper.

In this white paper we discuss two of the new features in SQL Server 2008, Star Join and Few-Outer-Row optimizations. We test the performance of SQL Server 2008 on a set of complex data warehouse queries designed to highlight the effect of these two features and observed a significant performance gain over SQL Server 2005 (without these two features).
