In 1991 Barrington licensed compiler technology from a company called Jensen & Partners International (JPI).
JPI was founded in 1987 by Niels Jensen, who had earlier (1979 or 1981) been one of the founders of Borland. Philippe Kahn was the marketing personnel who built Borland around the $99 Turbo Pascal compiler. Niels and his team were working on a new compiler technology at Borland when Philippe Kahn decided to buy Wizard C, and call it Turbo C. Niels and several other developers left Borland and started JPI, where they continued to work on their compiler technology, christened TopSpeed, which they bought from Borland for $1.7 million.
Clarion Database Developer 3.0 (CDD) was released in 1993. It was a revolutionary product adding many features and technology that could create programs with a “Windows like” CUA (Common User Access) user interface. Much of the CDD changes fit well into the Windows programming paradigm and laid the groundwork for the future Clarion for Windows product.
