Using Star Join and Few-Outer-Row Optimizations to Improve Data Warehousing Queries
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).

Transact-SQL Formatting Standards
How should SQL code be formatted? What sort of indentation should you use? Should keywords be in upper case? How should lists be lined up? SQL is one of those languages that will execute however you treat whitespace and capitalization.
