Harbour is a computer programming language, primarily used to create database/business programs. It is a modernised, open source and cross-platform version of the older Clipper system, which in turn developed from the dBase database market of the 1980s and 1990s.
Harbour code uses the same databases and can be compiled under a wide variety of platforms, including Microsoft Windows, Linux, Unix variants, several BSD descendants, Mac OS X, MINIX 3, Windows CE, Pocket PC, Symbian, iOS, Android, QNX, VxWorks, OS/2 (including eComStation and ArcaOS), BeOS/Haiku, AIX and MS-DOS.
