Throughout the last few years, I’ve worked with SQL Server Availability Groups, Transactional Replication, and Azure SQL Databases. Recently, I had the challenge and opportunity to work on a project that involved all three at the same time. The goal was to take six databases that were in a SQL Server 2012 Availability Group and […]
It’s my T-SQL Tuesday! I’ve spent the last year learning and teaching Extended Events – because if you really want to learn something, teach. XE can be used for everything from very simple tasks, such as counting the number of query executions, to very complicated tasks, such as anything Jonathan Kehayias writes about! I’m encouraging […]

You’ve been told time and again to back up your SQL Server system databases – master, msdb, and model. I’m here to tell you it’s not […]
For the preparation of my upcoming talk about SQL Server 2012 Master Data Services on the Microsoft Business Analytics Day (hosted by my company element61), I read the book Master Data Services 2nd edition by Tyler Graham. I had almost no prior experience with MDS up to this point (I very quickly glanced over it […]
This month’s T-SQL Tuesday is being hosted by SQLChow (b | t) and the topic is “Automation, how much of it is the same?”. As SQLChow noted, automation was a topic a few years ago and now it is being revisited to see if and how it has changed over the years. I know for […]
In 2013 I took on a slightly different approach to writing by putting more into each article with content, length and defining either what the topic was on or how the troubleshooting methods are taken. This, of course, meant my average blog count per mo…
