I would expect someone that has the title of data scientists to at least be a master in the universal data query language SQL. But im so used to ORM these days anything more complex then a sql join is already going over my head if i didn't do a sql refresher. As far as i have skimmed the article it seems like a very good refresher for even a SWE. I will definitely put this tutorial on my todo list.
