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]
Examples: Prolog, OPS5, Mercury, CVXGen [7] [8], Geometry Expert. A fifth-generation programming language (5GL) is any programming language based on problem-solving using constraints given to the program, rather than using an algorithm written by a programmer. [9] They may use artificial intelligence techniques to solve problems in this way.
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 ...
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.
2GL—second-generation programming language; 2NF—second normal form; 3GL—third-generation programming language; 3GPP—3rd Generation Partnership Project – 3G comms; 3GPP2—3rd Generation Partnership Project 2; 3NF—third normal form; 386—Intel 80386 processor; 486—Intel 80486 processor; 4B5BLF—4-bit 5-bit local fiber
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.
OpenEdge Advanced Business Language, or OpenEdge ABL for short, is a business application development language created and maintained by Progress Software Corporation. Typically classified as a fourth-generation programming language , it utilizes an English-like syntax to simplify software development. [ 1 ]
