Paradox is a relational database system for OS/2 and DOS with a version later showing up for MS Windows that was very different from the other two versions although mostly compatible with the exception of the programming language.
Paradox was quite a different take on the database that most of the other database packages popular at the time, it was heavily influenced by the spreadsheet package Lotus 1-2-3 in looks and function and this was not the least apparent in the programming language that was shipped with the database, known as Paradox Application Language (PAL) and although a fairly common 4th generation business language in some way it could be recorded from keyboard actions like a Lotus 1-2-3 macro.
History
Originally released in 1985 by USA independent publisher Ansa Software in 1985, it was taken over by Borland in 1987, who went on to port it to OS/2.
A version for the Mac was not shipped. The Reflex flat file database that on DOS was a budget software with limited programming abilities, existed in a version for the Mac was already quite an advanced relational database.
Paradox SQL
An add on program developed for Paradox OS/2 in 1988 that emulated the SQL interface of IBM DB2 and allowed Paradox for OS/2 1.0 to replace IBM's product as a database server, this was later given more generic SQL features and ported to other operating systems.
