Do you struggle to reduce those frustrating long hours it takes to load data? Are your time windows for loading becoming too short for comfort? If so – you simply can’t afford to miss this session…
Great database performance starts with great database design. During the design process it is important to select your SQL Server datatypes wisely. Failure to do so will result in wasted disk space, additional I/O overhead, and decreased performance.
At the heart of SQL Server is the cost based optimizer. This is driven by estimates and they in turn are driven by statistics.
This will be a deep dive into how the optimizer makes its decisions to give you a plan, the things that can go wrong.

SQL Sentry will present their revolutionary new software which provides enhanced visibility and manageability for advanced AlwaysOn topologies.
Is your data badly behaved and embarrassing you? Are you tired of cleaning up its messes? Constraints can help you straighten out your wayward data and put it on the right path before it gets into too much trouble.
This session will include a variety of such activities including Gathering Performance Counters in several servers at the same time using posh jobs, identifying Blocked Sessions and Reading & filtering SQL Error Log even if the Instance is offline
In this session we will advice how to avoid common developer mistakes and show how bad designed queries reduce the SQL Server optimizer's capabilities for choosing an optimal execution plan.
Do you have enough from "normal" performance tuning sessions? You can't hear anything about Indexing and Execution Plans anymore? Then you are right in this session!
This session will cover a collection of minor bad habits that can occasionally lead to major problems, and a set of best practices that you should always have in mind.
Karen discusses five (plus a few more) database design blunders with tips on how to avoid them. Audience members will also be able to contribute their war stories of design fails, WTHs and D'ohs.
