Project Info: New Releases of All GNUe Tools Available
3rd June 2002
The GNU Enterprise team is proud to announce a major release
of it's enterprise application development suite. This release
includes:
- GNUe Forms 0.3.0
- GNUe Designer 0.3.0
- GNUe Common 0.3.0
- GNUe Reports 0.0.1
- GNUe Application Server 0.0.1
GNUe-Forms is a platform and UI-independent forms system. It
reads an XML-based forms definition and creates GUIs for Win32,
GTK, and, soon, Curses and HTML. It has a fully data-aware widget
set and can be used in both 2-tier and n-tier environments.
GNUe-Designer is the IDE for the GNUe tools. It allows you to
visually layout your forms in a RAD-style environment. Designer
has a builtin forms client, so you can quickly test your forms
while still in Designer. Designer also has support for form
creation wizards... answer a few questions, attach your form to
one or more database tables, select the fields to include, and,
voila, a basic form is created.
GNUe-Reports is a platform and output-independent reporting
system. It reads an XML-based report definition and generates
arbitrary XML output that can further be translated into any
format for which there is an adapter. GNUe Reports currently
has outputs for Text, HTML, and CSV -- with PDF, Postscript,
and Gnumeric/Excel formats in the works. Reports can output
directly to a file, as an email attachment, to a printer, or
to a HylaFax server.
GNUe Application Server is the data and business rules server
for the GNU Enterprise project. It will provide an object-
oriented backend to forms and reports. In an n-tier environment,
GEAS holds all business rules/logic and provides object-to-
relational access to various database backends. This release
is primarily a proof-of-concept release that illustrates the
use of GNUe-Common's database backends and RPC abstraction tools.
GNUe-Common is the basis for the GNUe tools, such as Forms,
Reports, Application Server, and Designer. It implements a
database-abstraction layer that provides support for most
major databases. A builtin XML-to-Object parser and
Object-to-XML marshaller are used by Forms, Reports, and
Designer to save and read Forms/Report definitions to and
from an XML file. It also defines and implements an RPC
abstraction layer that will allow server processes to define
their public methods once and have them available to CORBA,
XML-RPC, SOAP, and DCOM clients.
All of these releases are targeted at developers. The five
products are available in source form from our website at
http://www.gnuenterprise.org/downloads/current.php.
We also have Windows installers for GNUe-Designer and GNUe-Forms
that include all the basic dependencies -- you only have to download
a single setup.exe! The Installers include support for PostgreSQL,
MySQL, and ODBC. These installers are available in the same locations
listed above.
