The session should be of benefit to both inexperienced and experienced SQL coders and analysts, each construct will be explained as well as the query plans produced. Demo's will be done on AdventureWorks which we actually discover is going out of business!
attend this session to understand exactly how the optimiser decides on its plans

See how the optimiser chooses the operators it does through real world examples.
A number of techniques have been discussed for scaling SQL Server on big-iron systems. Some apply to transaction processing, others to data warehouses. However there is very little available guidance on the impact of each for specific application characteristics. Learn which techniques are absolutely essential and which contribute a only few percent.

PANIC IN THE DATACENTER! Your databases are approaching - or surpassed - the Terrible Terabyte mark. You're pouring money into the SAN, but your data isn't pouring back out as fast as you want. You're terrified to DBCCs or index maintenance because everything takes forever, and you don't have big maintenance windows.
Need to eek out a bit more oomph from your dataflows. This session might be of some use.
Transaction Replication is a widely used feature in SQL Server though its internals are sparsely understood. In this session we will look under the hood and gain indepth understanding about Transactional Replication architecture and its corresponding components like logreader and distribution agents, Reader/Writer threads, etc. We will learn methods of identifying and monitoring replication latency and methods of troubleshooting and eliminating bottlenecks to improve Replication Performance.
An overview of some everyday TSQL tuning techniques.
SARGability relates to the ability to search through an index for a value, but many DB Pros don’t really get it – especially in regard to joins – leading to queries which don’t run as well as they should. No slides here, just demos...
Why and when denormalisation makes sense.
Do you wonder about SSIS performance? Well I do, and I've compiled my research into this session. We'll cover various design patterns for solving common problems like inserts vs. updates, is it faster to use a lookup, or can you just catch the errors and process them afterwards? As well as the richer patterns we'll look at some straight comparisons between two components that can be used to do perform the same task and ask which one is quicker?
This session will investigate using Stream Insight, SQL Server and Analysis Services to provide an example framework to monitor cube usage as well as suggest a mechanism for highlighting areas for performance and security enhancements.
Fast Track is a new reference data warehousing architecture provided by Microsoft. More than this it represents a new way of thinking about data warehousing. A Fast Track system is measured by its raw compute power - not by a DBAs ability to tune an index. Fast Track is an appliance-like solution that delivers phenomenal performance from a pre-defined, balanced configuration of CPU, memory and storage using nothing but commodity hardware. Of particular interest in a Fast Track system is the way in which the storage and SQL Server are configured. To achieve the fantastic throughput without using SSDs requires some careful configuration. This configuration is designed to make use of Sequential I/O to dramatically improve disk I/O performance. Interested? If you have a large data warehouse that's seen better days or perhaps you are about to embark on a new warehousing project then you should be! Fast Track is a great solution with a fantastic value proposition. In this one hour session we'll aim to get under the skin of Fast Track and get some answers as to how it delivers such great throughput on commodity hardware. In the process we'll aim to answer the following questions: * When might I need Fast Track? * What is Sequential I/O? * How does Sequential I/O improve performance? * What do I need to do to get Sequential I/O? * How can I monitor for Sequential I/O ? * What may I need to change in my ETL to get the benefit of sequential I/O? Still reading? I'll save you a front row seat....
Increase the "out of the box" performance and throughput of SQL Server.
Encapsulating common code in fucntions is one of the first things you learn as a programmer. However with SQL Server functions can be very bad for performance.

You will come away from this session understanding the pitfalls of TSQL functions and how you can make them run 100 times faster.
A challenge to traditional patterns of processing, storing and retrieving the precious data that we are responsible for
