Anyone who has worked with Oracle has encountered the Oracle “hr” schema in one way or another. The Oracle example schema provides a few simple tables with example data to test out some queries or learn SQL.
So when working with MySQL, I like to have the same schema as well. Luckily, Andrei Ciobanu feels the same way and he provides a wonderful adaptation of this sample schema for MySQL on his website: HR Schema for MySQL and Maria DB.
Thank you Andrei!
