FoxPro
FoxPro was a text-based procedurally oriented programming language and database management system (DBMS), and it was also an object-oriented programming language, originally published by Fox Software and later by Microsoft, for MS-DOS, Windows, Macintosh, and UNIX. The final published release of FoxPro was 2.6. Development continued under the Visual FoxPro label, which in turn was discontinued in 2007. FoxPro was derived from FoxBase (Fox Software, Perrysburg, Ohio), which was in turn derived from dBase III (Ashton-Tate) and dBase II. dBase II was the first commercial version of a database program written by Wayne Ratliff, called  Vulcan, running on CP/M, as does dBase II. FoxPro was both a DBMS and a relational database management system (RDBMS), since it extensively supported multiple relationships between multiple DBF files (tables). However, it lacked transactional processing. FoxPro was sold and supported by Microsoft after they acquired Fox Software in its entirety in 1992. At that time there was an active worldwide community of FoxPro users and programmers. FoxPro 2.6 for UNIX (FPU26) has even been successfully installed on Linux and FreeBSD using the Intel Binary Compatibility Standard (ibcs2) support library. Version information. Technical aspects.
