Your SQL Mastery Session on Understanding Execution Plans matched the abstract very well.

I am looking forward to a session on How To Use Execution Plans To Improve Performance. It would be very practical, and introduce properties in the Execution Plan as they are needed to help improve performance. Rather than being complete and explaining even the rarest operator, it would address the properties most commonly needed to improve performance.

I am looking forward to receiving yesterday session's example code.

Thanks for the feedback, Marc!

You are right that I don't focus on troubleshooting scenarios. I made a deliberate choice to focus on the building stones of the plan, and give the attendees the knowledge to understand both the individual elements, and the understanding of how they interact. Hence my analogy to learning language at the start.

My belief is that this knowledge may take more time to process and land, but once it does can be applied in more situations. Consider it a longer-term investment.

This is a very personal opinion, and your mileage may vary. But this is they way I have always liked to learn, and hence this is now also the way I like to teach.

But I do understand your feedback, and I will keep it in mind.

I have sent to the SQL Saturday organization a copy of the slides and a copy of the SSMS solution file with all the demo code (including the demos I had to skip for time reasons). I don't know whether they have already distributed this to the attendees, but if not they will undoubtedly do so later this week.

Thanks for your comment, and for attending my SQL Mastery Session! ;)

Java is considered a transitional language in Computer programming. It is the most demanding programming language after SQL. From the past 20 years, this programming language has survived the competition in the market. And this also means that the coursework in Java programming is a difficult one.
