DataSaturday Oslo is coming back on September 2nd! And with the free main event we also offer full day classes on select topics at a very low price! Here is Brent Ozar's Mastering Query Tuning class:

You need to speed up an existing app, and you’re allowed to change both queries & indexes, but you can’t throw hardware at it. Let’s tackle it together in a fast-paced 1-day version of my full 3-day class, and because we can’t cover everything, attendees get a year’s access to the full 3-day recorded class too.

Please note that this is a paid course and you must register on Brent Ozar's portal to be able to attend. Register for pre-con here!
