Welcome to "SQL Databases for Practice." This unique resource on our platform is designed to help you learn to analyze data using SQL on your own. In real-world situations, data analysts explore databases independently, formulate their own questions, and craft the answers using SQL. This skill is critical for any data analyst.

This course offers a variety of databases from our other courses for you to practice with. Unlike our other courses, there are no guided exercises here. Instead, you are encouraged to explore the databases at your own pace, find patterns, and gather important insights from the data.

This online course is the perfect space to apply and refine the SQL skills you have developed. Learn how to use your SQL skills to explore the database, ask questions, and write SQL queries to answer them. Curious about how JOINs really work? Need a database to practice CTEs? You have come to the right place!

One of the biggest challenges in learning SQL is finding a hassle-free place to practice. You often have to deal with technical installations and database setups, which can be a real pain. But with our SQL course, you can skip all that. Start writing and testing your queries right away in a user-friendly environment. It is all about focusing on boosting your SQL skills and getting a better grasp of how it all works.

This new resource is an experiment, so please send us your feedback at contact@learnsql.com. Let us know what you think about this format and any other SQL datasets you would like to see in this course.

This course is intended primarily as a resource within our All Forever SQL Package, but you may purchase it for use as a standalone supplement.
