Java for Everyone: Q-Link Version 5.0 Brings J2EE Development to the Masses

(May 7, 2003) - Version 5.0 of Q-Link Technologies' Q-Link application development platform promises dramatic reductions in the overall complexity, time, and cost of developing J2EE applications. "I was able to build a complete application in less than one day with Q-Link, it would have taken a week using other tools," commented Sapana Patel, project manager for Interval International.

The Q-Link platform eliminates the complexity of traditional J2EE development by bringing together three unique elements:

1. A new application model - an abstraction layer that enables developers to visually assemble complete applications based on business constructs, not complex J2EE code.

2. A suite of integrated Business Process Management (BPM) services such as component-based workflow and UI design, integration, business rules, and persistent data.

3. A scalable architecture built on standards-based technologies such as J2EE, XForms, and XPath, ensuring long-term, cross platform compatibility within the enterprise.

A primary differentiator of the Q-Link platform is the combination of component assembly and design-time integration capabilities that eliminates much of the coding, scripting, testing, and debugging typically required when building Web applications. Q-Link's architecture enables developers, utilizing re-usable components, to assemble every aspect of an application from the design of the user interface to the definition of the workflow and business rules.

With the 5.0 release, Q-Link introduces several new features, which include an innovative approach for creating an application's user interface and forms. The functionality, based on the new XForm standard from W3C, enables developers to visually assemble robust forms by dragging components from a toolbox onto a form canvas. As each element of the form is added, a unique dialog is displayed allowing developers to configure the form element properties. In addition to many out-of-the-box form components, Q-Link provides developers with a framework to add their own business-specific form components. These user-defined form components can perform simple functions like displaying a customized list of sales territories or company departments or execute more complex functions such as interact with a Web service, retrieve inventory levels from an ERP system or customer call history from a CRM application. Once the form component is defined, it can be re-used within any new application.

Q-Link 5.0 will begin shipping in June.

Reading the article looks a lot alike old 4GL tools, like Uniface as example.

I think new tools based on MDA (Model Driven Architecture) from OMG are offering many advantages.
Unfortunately too many claim to be MDA compliant, but few really are...
...unless you accept as compliant paper and pencil too!

Take a look at Compuware's OptimalJ to have an idea of a MDA compliant tool.

As far as I know is the only one implementing real model transformation required by MDA in an automated way by J2EE architectural patterns.
