Introduction
x4GL technology (where x stands for various vendors implementations of I-4GL
product) evolved significantly from the days when I-4GL was the proprietary and
legacy technology, as well as the only implementation of the I-4GL compatible
language available. Significant number of x4GL vendors emerged in last 10 years,
including vendors making compatible products, extending functionality, providing
services including migration and conversion, and even the OpenSource project
with purpose of promoting and enhancing x4GL technology was established.
This document was created to enhance the visibility of all this activity, and
make it easier for a vendor to evaluate its future involvement with x4GL
technology. Primary purpose is to collect in one place sufficient information about various
available x4GL compatible products, vendors and services, for the reader to
learn what is available and what functionality to expect. It is not to be used
as a sole source of information for this purpose.
All features and other characteristics of vendors and products where
evaluated from the perspective of Business Related, Database Oriented
applications development environments. Naturally, needs of different
developments environments, even within same organization, are different, and
changing. Therefore, no scoring or other measurement method was used.
The first part, the features tables, is mostly dry facts; the following
sections, however, are much more "opinionated" by necessity. Since the choice
was made not to use scoring, it was the only way to emphasize and contrast
various strengths or weaknesses of products. As all opinions are by definition
personal, always evaluate them in the context of your specific needs and
resources. Hopefully, some will be useful, some thought provoking, but some will
not apply well to your environment. Cevat Emptor.
This document assumes some level of familiarity with x4GL technology, but one
is not expected to be a x4GL developer to benefit from it. Almost all technical
details are concentrated in "x4GL products by feature" tables, and most other
information discusses business, process and management issues. Therefore, the
target audience will range from corporate technology decision makers all the way
to development team leaders and development project managers, and curious
developers.
Disclaimer:
All reasonable effort was made to ensure that information provided was
correct. However, some information had to be condensed because of limited space,
to simplified answers, and some vendor claims where not verified. Information is
believed to be accurate at the time if the writing (June 2005), however, no
responsibility can be accepted for possible errors or omissions. Corrections
will be gratefully received.
