The SQL Server Internals interactive drills are live — on-disk structures, I/O mechanics, optimizer behavior, execution plans.
You can’t optimize what you don’t understand how to wreck.
Most people learn SQL Server internals when something breaks and can’t wait. I prefer to break things deliberately, with full attention, before the pressure is on.
The interactive drills on siberiasoft.com/projects/sql-internals cover exactly what happens between your keyboard and your result set — on-disk structures, I/O mechanics, optimizer behavior, execution plans.
