What students have to say . . .



“Enjoyed the training. It was a different approach that I found very useful. I was looking for information about how and when you would use AG. The troubleshooting aspect was very good and as someone has already said, it helped me to understand the dynamics between all the working parts.” – Paula



"One of the best online SQL courses focused on a critical aspect of database administration. Very well presented which includes anticipated errors and 'scratch your head' SQL behaviors that experienced DBAs will figure out eventually at the cost of wasted time. Having said that, this is a worthy investment indeed." - Mel



“This training was amazing. I had previously had some experience with availability groups, but Edwin’s knowledge really helped me understand the dynamics between all the working parts. I am more confident to work with availability groups, and I fully understand many situations that I did not before.” – Michael
