This hands-on course offers an introduction to SQL for absolute beginners, exploring how to ask questions, organize information, and retrieve instant answers from a database.

Learn SQL basics with our beginner-friendly guide to understanding the language of data. You’ll start by learning to talk to a database: asking questions and getting meaningful answers using SQL. With AI-assisted guidance, you’ll explore the essentials—selecting columns, filtering rows, sorting results, and applying logic to uncover patterns in raw data.

As your questions become more precise, you’ll explore grouping, aggregation, and subqueries to extract deeper insights. Then you’ll shift gears and learn how to create tables, insert and edit data, and design simple relational schemas. Finally, you’ll tackle real-world scenarios using joins, building multi-table queries, and designing interactive dashboards. You’ll complete hands-on challenges and projects like a student tracker and a game leaderboard. No prior experience with databases or programming is needed—this course is your friendly introduction to the language of data.
