The ANSI X3J19 committee worked on standardizing a common "dialect" of the languages represented by dBase, Clipper, FoxBase, and possibly others as xBase, and some of the more recent systems complying with this standard have the ability to use SQL and to interface with outside databases.
This is essentially a Clipper "clone;" it compiles much dBase III+ (and higher) code, and reads related file formats.
Free Personal FlagShip is a unlimited 2-user version similar to the commercial Personal license, but intended strictly for personal use or for development of database applications distributed for free (i.e. public domain, Open Source or GPL licensed).
Harbour Project - Building a Clipper "clone" for DOS and Unix that is be freely redistributable...
A fork of Harbour that takes a more aggressive approach to enhancements.
A Clipper compiler that works fairly similarly to the original Clipper system, generating binaries (for Linux or Windows) for the specified program.
dollyBase is a free dBase Clone that can manipulate Dbf files and support ndx index files, prg program files and query files.
The present owners of the dBase name and software are promoting the creation of dBase software in some sort of "open source" form, and the future plans indicate some interest in a Linux deployment.
The sellers of dBASE also plan to release an accounting system called dBa under some form of "open source" license.
Building web-based applications using xBase file formats on Linux
C application for parsing dBase III files
VersaSoft used to sell dbMan V, a "clone" of dBase III, for various platforms, including Linux. They appear to no longer be operating.
www.versasoft.com gets you to the "web home" of Versatech Software, which is not a related operation.
CDBFile is a C++ object-oriented package for
programmers who need to manipulate dBASE III files in
their programs. It enables you to perform many operations on an
existing DBF file: reading/writing to it, accessing its values,
sorting the records, adding/deleting records, etc. It comes with full
text and postscript documentation, and commented source code.
A demonstration program, TestDBF, shows the various possibilities of the CDBFile library, and its source file, testdbf.cpp, demonstrates how to implement CDBFile within a program.
Xbase DBMS is a collection of specifications, programs, utilities and a C++ class library for manipulating Xbase type datafiles and indices.
XBSQL is a wrapper library providing an SQL-like interface to the XBASE DBMS.
