SQL is one of the most sought-after skills for data analytics. Good news: nowadays, you don't need to build your own database to learn SQL, and plenty of resources are available. My top-3:
Theory + hands-on practice "SQL track" from datacamp
practice with top interview questions on leetcode
If you are already advanced in SQL, which resources did you use to learn and master it? I'm curious to hear from you in the comment section below!
P.S: На русском языке есть прекрасный бесплатный курс "Симулятор SQL" от karpov.courses с краткими, но толковыми пояснениями и огромным количеством упражнений
