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.
Declarative programming stands in contrast to imperative programming via imperative programming languages, where control flow is specified by serial orders (imperatives). (Pure) functional and logic-based programming languages are also declarative, and constitute the major subcategories of the declarative category. This section lists additional ...
The LDL language is promoted to LDL+, with new object-oriented features. The Development environment makes use of the Microsoft Visual Studio IDE. The Model Driven approach is extended with a UML based Class Diagram integrated with all the source code of the solution, in such a way that a round trip update is achieved.
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 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.
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.
