Mmm... Ashton-Tate dBase III+, those were the good old days:) And later, similarly with db and programming integration: MS Access, and even Excel to some extent.
None of them ever made it past the 'desktop' as a whole though, probably a feature of any db-included programming language.
I hear you. Yea, I never got round to using Clipper but was on track, especially the possibility to create standalone applications as front-end clients in a client/server setup was interesting. It was bought and botched by CA before I got round to it though, at least it looked like CA mishandled it from what I could see.
A fun related fact albeit OT was that those DOS applications were orders or magnitude faster to keyboard operate than the GUI applications that came after ... I'm sure some of them are still in use for that reason.
