Hey everyone, Tobias here, the author. I am a developer fascinated by databases for over a decade and I have consumed (and still consume) everything I can find about them - including every article shared here. When helping other developers, I see that they all struggle with creating correct database indexes for slow queries. But I could never recommend articles or books to learn it as they only discuss very simple examples or focus on super complicated stuff that is only needed by a tiny fraction of developers. So, I wrote this book to have something I can recommend to everyone. And I did it in a completely different way: - Focus on only practical stuff a developer needs - Explanation of the basic principles of how indexes are used - Examples of how all SQL operations use indexes and how they behave when combined (that's always missed in literature) - Dozens of visualizations for an easier understanding and to replace boring walls of text You can download preview chapters on the landing page to experience the difference.
