How Our SQL Summary Course Works

Despite being over 50 years old, SQL remains the de facto language of databases. And with data being collected, stored, and analyzed like never before, SQL is, by all accounts, one of the most in-demand skills in data science. Most data professionals use SQL more than any other language.

That’s why we’ve created the SQL Fundamentals skill path, which this course is a part of. At Dataquest, we design all of our courses to help you quickly and effectively advance on your data science path. We’ve taken great care to ensure that you can maximize your learning potential by supplying the structure and support you need while allowing you the freedom and independence to learn at your own pace.

Unlike most online courses, here at Dataquest, we believe in learning by doing. When you learn with us, you’ll never sit through boring training videos or complete ineffective “fill-in-the-blank” questions. Instead, you’ll learn SQL the right way: solving real problems using real code—and you’ll start on day one.

Additionally, with Dataquest, you’ll never learn alone. We have a thriving community of data learners and professionals eager to accompany you on your learning path and help you overcome any obstacles you encounter. And if you ever need a little extra help, our powerful and responsive support tools are just a click away.
