The SQL for Data Analysis course on Udacity is a great introduction to the language for anyone who wants to learn how to extract and analyze data stored in databases. The course is taught by Jeff Smith, a former Google data engineer, and it covers all the basics of SQL, including SELECT, INSERT, UPDATE, DELETE, and JOIN statements. Smith does a great job of explaining the concepts behind SQL in a clear and concise way, and he provides plenty of hands-on exercises to help students practice what they've learned.
The course is divided into four modules:
Each module includes video lectures, interactive exercises, and quizzes. The quizzes are not graded, but they are a great way to test your understanding of the material.
The course is self-paced, so you can work at your own pace. It is also free to audit, so you can watch the videos and complete the exercises without paying anything. However, if you want to earn a certificate of completion, you will need to pay the $49.99 course fee.
Overall, I think the SQL for Data Analysis course on Udacity is a great resource for anyone who wants to learn SQL. It is well-taught, comprehensive, and affordable. I highly recommend it.
