Stairways

To keep up to date with all the technologies in SQL Server, the DBA or developer who wants to stay ahead is faced with the struggle of constant learning. How do you keep up while avoiding information overload, unnecessary detours and dead-ends?

The SQL Server Stairways is our solution to this problem. Designed to smooth out even the steepest learning curve, each Stairway is a SQL tutorial series focused on a single topic and is arranged into no more than a dozen easily-navigable tutorials that we call 'steps'. Each step is the length of a typical magazine tutorial, and emphasizes practical, hands-on learning, with just enough background theory to help you understand the topic at a deeper level.

Using straightforward language and avoiding jargon and marketing babble, each Stairway tutorial series is designed to take you from zero knowledge of a particular SQL Server topic to a level of practical understanding that will allow you to start using that feature in a production environment. The learning gradient is steady and manageable, but also brisk. You won't be wasting time.

Happy climbing!

Stairway to SQL Server Extended Events

Stairway to SQL Server Extended Events

Erin Stellato, a Principal Consultant with SQLskills.com, explores the use of Extended Events as a diagnostic data collection tool or SQL Server. She describes how to define efficient low-overhead event sessions that exploit fully the vast number of events, as well as the powerful filtering and data collection options, offered by this new event collection infrastructure. She also demonstrates simple techniques to analyze event data and identify and troubleshoot the causes of poor SQL Server performance, such as long-running queries that consume vast amounts of CPU and I/O resources. It is time to embrace Extended Events and understand all that it has to offer, and Erin's stairway is the perfect place to start.

Stairway to Columnstore Indexes

Stairway to Columnstore Indexes

SQL Server 2012 and later offer a very different type of index from the traditional b-tree, the in-memory columnstore index. These indexes use a column-based storage model, as well as a new 'batch mode' of query execution and can offer huge performance increases for certain workloads. But how are they built, how do they work, and why do they manage to have such a dramatic impact on performance? In this stairway, Hugo Kornelis explains all, with his usual mix of concise description and detailed demonstration.
