Fourth Generation Programming Languages.
fourthgeneration00jaco.pdf (3.933Mb)Abstract
With an ever increasing demand for new program applications
and the failure of older generations of languages,
such as COBOL, PL/ I, PASCAL, etc., to keep up with this increased
demand, there exists a need for new techniques and
approaches to programming. Greater programmer /user productivity
and enhanced user friendliness, to allow more end
users to develop applications on their own, are goals sought
by industry in order to reduce skyrocketing backlogs of
applications. This paper describes a new generation of programming
languages, used in the development of business and
scientific applications, that addresses and achieves these
goals. The basic characteristics of Fourth Generation
Languages is reviewed and the design and implementation of
a Fourth Generation Language is proposed. Although Fourth
Generation Languages do increase user productivity and are
easier to learn and use than previous generations of languages,
much research remains to be done before general end
user computing becomes the norm rather than the exception.
