mmpark's honest review, [Concept Class] SQL Queries You Can Learn and Use Immediately course

I haven't touched data for several years except for one information system class while I was in college, so I'm satisfied with the fact that I've been able to build a basic understanding of SQL with concise and accurate explanations. I still have difficulty writing queries myself (because the company's data structure is complicated), but I think I've gained some literacy in reading queries that have already been written.
