In early February 2024, a SQL tutorial named "SQL for Data Scientists in 100 Examples" reached the top spot on Hacker News. I was impressed with the project and felt that its examples would be a great starting point upon which to create Kotlin dataframe tutorial.

My goal was to clone the 100 SQL queries and produce the same results via Kotlin dataframe, providing a resource for data analysts, scientists, programmers and software engineers who are looking to utilize dataframe in their projects.
