I maintain a SQL version of the John Hopkins novel coronavirus dataset. It's a fun dataset to write queries against as it changes daily. I published a blog entry about how to use it and some of the SQL I used.<p>https://www.dolthub.com/blog/2020-02-23-novel-coronavirus-dataset-in-dolt/<p>It uses Dolt, git style versioning on top of a SQL database. It's hosted on DoltHub, GitHub for Dolt. My company built both those tools as well.
