So if you want or need to level-up your analytical skills, start learning PostgreSQL queries today!
In this beginner-friendly tutorial, you will find out what you need to start "talking" with the PostgreSQL database. That is, you will learn what relational databases are, how tables work, and how to write simple queries. If you're already feeling overwhelmed, don't worry!

Everything will be explained systematically. Ultimately, after you complete PostgreSQL Queries, your boosted data analysis skills will let you go beyond those pesky spreadsheets.
We'll start by explaining how to use the SELECT statement to retrieve information from an individual table. The next step will be working with multiple tables; you will learn how to JOIN them, GROUP BY a specific metric, build unions and intersections, and perform an aggregation. Moreover, you will be introduced to dealing with subqueries.
At the end of each section, you will find a short quiz that will both check as well as consolidate what you've learned. If you complete all the exercises throughout the online course, you will be awarded with a certificate. You can publish your certificate on your LinkedIn profile, or print it out and show it to your boss.
