Understanding Join Operators
December 7, 2010 12 PM noon Eastern Time (GMT -5)
Ami Levin

SQL Server implements three different physical operators to perform joins. In this session, we will examine how each of these operators works, including its advantages and challenges. Using real life examples, we will better understand the logic behind the optimizer's decisions on which operator to use for various joins. Finally, we will learn how to avoid some common join related pitfalls and how to get better performance from our queries.

Dr. DMV: How to Use Dynamic Management Views to Monitor and Diagnose Performance Issues With High Volume OLTP Workloads
December 8, 2010 12 PM noon Mountain Time (GMT -7)
Glenn Berry

SQL Server 2005 introduced Dynamic Management Views (DMVs) that allow you to see exactly what is happening inside your SQL Server instances and databases with much more detail than ever before. SQL Server 2008 R2 adds even more capability in this area. You can discover your top wait types, most CPU intensive stored procedures, find missing indexes, and identify unused indexes, to name just a few examples. This session (which is applicable to both 2005, 2008 and 2008 R2), presents and explains over thirty DMV queries that you can quickly and easily use to detect and diagnose performance issues in your environment.

Using OLAP to Optimize and Maintain Predictive Analytics Models

In complex Predictive Analytics (PA) scenarios where it is being applied to a complex system or the players involved are actually trying to undermine the predictions (ex: credit card fraud), the sophistication of the PA must be taken up a notch or two. In this Webcast I will describe techniques for building sophisticated PA systems on the Microsoft BI Stack by using OLAP to:
- Analyze, validate, and optimize PA models.
- Manage and Monitor the performance of the PA models in a Performance Management style.
- Surface PA results to end users in a manner that allows them to work through the ambiguity that remains around predictions.
