Websites like Codecademy, Coursera, and Khan Academy emerged, providing interactive tutorials and structured courses that catered to beginners and advanced users alike. The proliferation of open-source database systems, such as MySQL and PostgreSQL, further fueled interest in SQL, leading to a wealth of free learning materials available through blogs, YouTube channels, and community forums. Today, free SQL courses continue to thrive, empowering individuals to enhance their technical skills and pursue careers in data science, analytics, and software development. **Brief Answer:** The history of free SQL courses began with the increasing need for data management skills in the tech industry, leading to the emergence of online education platforms in the early 2000s.
