Hi everyone, Anatoli is here, the author of SQL Habit.<p>Problem: SQL is a language of data but many resources out there teach it on examples that are far from reality of a modern Internet company.<p>Solution: SQL Habit teaches SQL from scratch with examples from a fictional Internet company. You'll start from 0 and learn about how data helps this fictional startup to solve day to day challenges in Product, Marketing or Business departments.<p>After 6 months of building and 600 commits on Github I'm really excited to share SQL Habit with HN! Looking forward to your feedback (+ it's Black Friday sale)!
