I was an undergraduate in the late 1980s/early 1990s and I worked part time in the university library working on databases and interfaces first in dBase III then Foxbase (the predecessor to Foxpro; basically an extended dBase III clone) then DOS FoxPro. I rather liked them, but this was long before I had ever seen SQL or anything like that. The weird thing was that my boss (besides being the library's IT guy) was a taekwondo instructor! What is it about FoxPro and that?
I'm wondering if it's the same guy. Without doxxing yourself too much, you didn't happen to be in the central Florida area did you?
