In isolation because of Corona last year, I started to share many lesser-known database tricks I know on Twitter (@tobias_petry). Although I thought that only a few people would be interested in something like this, it became a matter of course over the months. Meanwhile, thousands follow me to read my database tips or news.

Since every message in the constant social media stream vanishes after a few days, I had to do something about it. Knowledge must be preserved. I sat down for a few weeks and reworked every example and every text to create an ebook that you can read in an evening and still impart tons of knowledge.

And so "Next-Level Database Techniques for Developers" was born.
