Data Science 100 Knocks (Structured Data Processing) – SQL part2 (Q21 to Q40)

This is an ipynb file originally created by The Data Scientist Society(データサイエンティスト協会スキル定義委員) and translated from Japanese to English by DeepL.

Since this data is created for Japanese, you may face language problems when practicing. But do not worry, it will not affect much.
