DataflexDataFlex originated in around 1980 as a database cum programming language, self-described as an applications development database. It is a relatively early example of a fully fledged and commercially used fourth-generation programming language (4GL). In its early forms, DataFlex was available for UNIX, VAX/VMS, CP/M and the MS-DOS operating systems. To date, DataFlex has lasted the course as a niche application development environment. The DataFlex product supports the big four database environments, Oracle, MS-SQL, IBM DB2 and Pervasive SQL as well as any ODBC database. DataFlex applications are used by around 3 million users worldwide. The DataFlex programming language is used in the following development environments: DataFlex is produced by the Data Access Corporation located in Miami. Data Access Corporation was founded in 1976. DataFlex is an advanced object-oriented 4GL designed for developing database applications. The DataFlex language differentiates itself from other programming languages in the following ways: - Easy switch between database backends, no code change needed. No compilation needed.
- Variables are loosely typed. The virtual machine takes care of conversions.
- Flexibility; you can define your own commands.
- Code compiles to an intermediate Byte-Code which makes the programs easily portable between operating systems.
- No threads or multi-tasking
- Methods can be defined or redefined inside the object definition.
- Automatic delegation of messages in the Object Oriented Programming environment
- Embedded Database access is ISAM based. Can be used royalty free.
