I am an office worker doing data analysis. I am so glad that I got to know Janjaemi Coding through in-house training support. After the Python boot camp, I have now taken the SQL course. I am very satisfied with the fact that I can learn the big picture of the overall data analyst and learn step by step, and I can directly apply and learn the contents that are highly applicable to the field. In RDBMS, analysts often use the Hint statement, so I think it would be great if the content that briefly introduces the representative types of these was updated, and I highly recommend this course to others!!
