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).
Initially, all programming languages at a higher level than assembly were termed "third-generation", but later on, the term "fourth-generation" was introduced to try to differentiate the (then) new declarative languages (such as Prolog and domain-specific languages) which claimed to operate at an even higher level, and in a domain even closer ...

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.
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 ...
SheerPower 4GL is a fourth-generation programming language developed by Touch Technologies, Inc. [1] SheerPower 4GL is the result of porting Touch Technologies' Intouch 4GL programming language that runs on OpenVMS (for DEC Alpha and VAX computers) to Windows, launching in 2000.
Moore saw Forth as a successor to compile-link-go third-generation programming languages, or software for "fourth generation" hardware. He recalls how the name was coined: [15] At Mohasco ["in the late 1960s"] I also worked directly on an IBM 1130 interfaced with an IBM 2250 graphics display. The 1130 was a very important computer: it had the ...
This is an index to notable programming languages, in current or historical use. Dialects of BASIC, esoteric programming languages, and markup languages are not included. A programming language does not need to be imperative or Turing-complete, but must be executable and so does not include markup languages such as HTML or XML, but does include domain-specific languages such as SQL and its ...
