==History==
;1984: First Commercial Release (Version 2.2)
The original Progress 4GL was designed (in 1981) as an architecture independent language and integrated database system that could be used by non-experts to develop business applications by people who were not computer scientists but were knowledgeable in their business ___domain. At the time, business applications were often written in COBOL (for machines like corporate IBM mainframes) and sometimes in C (for departmental minicomputers running the UNIX operating system). When the IBM PC became popular, there developed a need for business software that could be used on those and other inexpensive computers. The Progress system was created to be used on both IBM PC machines running DOS and on a variety of computers that could run UNIX.
