DB/C was developed by Subject, Wills & Company in the early 1980s. It was an implementation of the DATABUS programming language that was invented by Datapoint Corporation to run on Datapoint computers. The purpose of DB/C was to allow programs developed in DATABUS to run on the DOS operating system of the brand new IBM PC, and soon thereafter on Compaq computers with MS-DOS. Then came support for running DB/C programs on UNIX, AIX, VMS, OS/2, Macintosh and other operating systems.
In 1999, the DB/C software product was renamed DB/C DX. The programming language name remained DB/C. The release of the DB/C FS software product a few years prior was a reason for the name change to DB/C DX. DB/C FS allows for access to files of DB/C programs via ODBC and JDBC interfaces of SQL, and directly from other programming languages by using APIs for accessing DB/C ISAM, AIM, RANDOM and SEQUENTIAL files that are native in the DB/C DX runtime environment.
In 2001, DB/C Software Company was split off from Subject, Wills & Company as a standalone corporation dedicated to the DB/C DX and DB/C FS software products. Several years later, DB/C Software Company was renamed Portable Software Company which continued to enhance and support DB/C DX and DB/C FS.
DB/C DX and DB/C FS were licensed on a per user basis until January 2023 when they became open source software.
