DataFlex is an object-oriented high-level programming language and a fourth generation visual tool for developing Windows, web and mobile software applications on one framework-based platform.

[5][2][6][7] DataFlex can be traced back to 1982 when the company called Data Access Corporation[8] (founded in 1976) created and developed a language allowing application code to run on almost any system architecture, regardless of hardware.

In its early forms, DataFlex was available for CP/M, MS-DOS, TurboDOS, Novell NetWare,[10] OS/2, Unix, VMS and IBM AIX operating systems.

[13] The release of DataFlex 2023/23.0 introduced FlexTron technology that allows the usage of web controls within Windows desktop applications.

DataFlex is developed and provided by Data Access Worldwide, a software company with main offices in Miami, Florida, Hengelo, Netherlands, and São Paulo, Brazil.
