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!

This Stairway will as also provide some history of the SQL language and some general concepts about set theory. Each level will build upon the prior level, so by the time you are finished you will have a good understanding of how to select and modify data from SQL Server.

Stairway to Transaction Log Management

Stairway to Transaction Log Management in SQL Server

When things are going well, there is no need to be particularly conscious of what the transaction log does or how it works. You just need to be confident that every database has the correct backup regime in place. When things go wrong, an understanding of the transaction log is important for taking corrective action, particularly when a point-in-time restore of a database is required, urgently! Tony Davis gives just the right level of detail that every DBA should know.
