A fourth-generation programming language (4GL) is a high-level computer programming language that belongs to a class of languages envisioned as an advancement upon third-generation programming languages (3GL). Each of the programming language generations aims to provide a higher level of abstraction of the internal computer hardware details ...
A third-generation programming language (3GL) is a high-level computer programming language that tends to be more machine-independent and programmer-friendly than the machine code of the first-generation and assembly languages of the second-generation, while having a less specific focus to the fourth and fifth generations. [1]
Programming languages have been classified into several programming language generations. [1] Historically, this classification was used to indicate increasing power of programming styles. Later writers have somewhat redefined the meanings as distinctions previously seen as important became less significant to current practice.
This is a "genealogy" of programming languages. Languages are categorized under the ancestor language with the strongest influence. Those ancestor languages are listed in alphabetic order. Any such categorization has a large arbitrary element, since programming languages often incorporate major ideas from multiple sources.
OpenROAD, which stands for "Open Rapid Object Application Development", is a fourth-generation programming language (4GL) and development suite from Actian Corporation. It includes a suite of development tools, with built-in Integrated development environment (IDE) (Written in OpenROAD), and Code Repository.
The DataFlex programming language is used in the following development environments: DataFlex Studio This is the flagship visual development environment from Data Access Worldwide. DataFlex is available for Microsoft Windows only. DataFlex is a GUI development language in a style comparable with Visual Basic, Delphi and C++. From version 4 ...
PROIV was originally developed as a fourth-generation programming language (4GLs). PROIV and other 4GL are aiming to simplify and reduce efforts to create and develop computer programs compared to third-generation programming languages (3GLs) such as Cobol and Fortran. [4] PROIV's usual application domain is database-centric business applications.
The LANSA's RDML Program was related to (Rapid Development and Maintenance Language). This development language allows you to create a High-Level Application Definition or abstraction of your business application. This definition is independent of the operating platform. Defining logic with a 4GL makes your programs independent of the 3GL layer.
