What will I learn?

Master SQL from beginner to advanced through a practical course using real-world data. You'll learn proper schema design, DDL, keys, constraints, and normalisation, then move on to crafting efficient SELECT statements, joins, filters, and date queries. After that, practise inserting realistic test data and ensuring data integrity. Finally, explore window functions, subqueries, indexing, time-series analysis, and query optimisation to deliver quick, dependable insights.

Your classes are perfect. I got the one-year package and finally have the chance to follow several topics I'm interested in without having to switch platforms... I appreciate everything you do, I've already recommended you to others...
