Fourth-generation programming language
A
fourth-generation programming language
(
4GL
) is a
computer
programming language
envisioned as a refinement of the style of languages classified as
third-generation programming language
(3GL). Each of the
programming language generations
aims to provide a higher level of
abstraction
of the internal
computer hardware
details, making the language more
programmer
-friendly, powerful and versatile. While the definition of 4GL has changed over time, it can be typified by operating more with large collections of information at once rather than focusing on just
bits
and
bytes
. Languages claimed to be 4GL may include support for
database
management,
report generation
,
mathematical optimization
,
GUI development
, or
web development
. Fourth-generation languages have often been compared to
domain-specific languages
(DSLs). Some researchers state that 4GLs are a subset of DSLs.
