I loved DBase II and DBase III+ but then I switched to DataEase and did some huge database systems mostly running on Netware. Whilst I used Clipper, FoxPro, and others, for that genre of non-client-server text mode databases DataEase v4 was the ultimate (for my tastes). It didn't do well in the Windows transition and doesn't get much of a mention these days, although dataease.com is still developing and releasing stuff (the old DOS editions were the pinnacle and stuff since then is forgettable).
