The ObjectPAL changes were controversial but forced since PAL was based on keystroke recording actions that had no equivalent in Windows. Although key features of the DOS product, the QBE and the database engine, were ports keeping the DOS code, there was a major break in compatibility from PAL to ObjectPAL and in the shift to a GUI design metaphor for Forms and Reports.

Paradox for Windows applications are programmed in a different programming language called ObjectPAL. Paradox for Windows is distinctly different from Paradox for DOS, and was produced by a different team of programmers. There are a few MSDOS emulators, among which are (a paid-for product) and (which has a freeware option), both of which provide the ability to run Paradox for DOS applications (such as Paradox 4.5 for DOS) on Windows Vista and above 64-bit operating systems.Įxample of QBE query with joins, designed in Paradox for Windows

At that time, dBase and its xBase clones ( Foxpro, Clipper) dominated the market. Paradox/DOS was a successful DOS-based database of the late 1980s and early 1990s. Version 4.0 and 4.5 were retooled in the Borland C++ windowing toolkit and used a different extended memory access scheme. Versions up to 3.5 were evolutions from 1.0. Notable classic versions were 3.5 and 4.5. In September 1987, Borland purchased Ansa Software, including their Paradox/DOS 2.0 software.

The New York Times described it as "among the first of an emerging generation of software making extensive use of artificial intelligence techniques," and noted that Paradox could read the competing Ashton Tate's dBase files. Paradox for DOS was a relational database management system originally written by Richard Schwartz and Robert Shostak, and released by their Belmont, California-based company Ansa Software in 1985.
