An earlier high-level application development system for 16-bit Windows applications from Unify Corporation, Sacramento, CA (www.unify.com). It was used to write applications that accessed SQL databases in a client/server environment. SQLWindows Solo was a demonstration version that provided all the functionality of SQLWindows, but worked only on a single machine. The software originated with Gupta Technologies, which Unify acquired in 2006. See SQLBase and Team Developer.
