❓ Frequently Asked Questions (FAQ)
What’s the best way to start learning SQL?
Begin with basic SELECT queries and filtering, then move on to JOINS, GROUP BY, and real project datasets. Platforms like SQLZoo and Mode SQL help.
Should I learn NoSQL or SQL first?
SQL is foundational for most data jobs. Start there, then learn NoSQL (like MongoDB) for flexible, scalable use cases.
What free tools can I use to practice databases?
Try SQLite, PostgreSQL, MongoDB Atlas (free tier), and practice on Kaggle datasets or hosted sandboxes like LeetCode’s SQL section.
Can I get a job by just learning SQL?
Yes, roles like Data Analyst, Reporting Specialist, or even entry-level DB Admin may require only SQL. However, more skills increase your chances.
