Expected Questions Q&A 💬

Q. Why should I learn SQL?

Even if you're not a data analyst, developing data literacy (the ability to understand and utilize data) is crucial. Because the IT industry relies heavily on data, developing data handling skills is a fundamental skill regardless of job role. Furthermore, for non-developers, mastering SQL can be a tremendous advantage.

Q. Is this a course that non-majors can also take?

Yes, SQL isn't difficult at all. Once you understand the basic principles of SQL, you can use it as if you were using Excel.

Q. Will this be helpful for backend developers as well?

SQL is essential for backend developers. However, many developers are so accustomed to ORMs that they often struggle to properly handle basic SQL. If you feel you lack a solid understanding of SQL, this course will be helpful.

    이 SQL 강의는 SQL 쿼리 작성하는 것에만 그치는 것이 아니라 SQL을 이해하는데 도움이 많이 됩니다. 또, 제대로 이해한다면 실전적인 예제가 많이 있어 실무에서도 잘 활용할 수 있을것으로 예상합니다.

      기초적인 지식과 함께 문제를 혼자 풀고 그다음에 강의에서 확인해보는 흐름이 좋았습니다. 쉬운문제, 조금난이도 있는문제를 풀어보면서 어떻게 적용해야하는지, 그리고 같은 결과를 내는방법도 여러가지 방법이 있다는것도 배울수있었습니다. 좋은 강의라고 생각합니다.
