ABSTRACT With the emergen e of the Internet and proliferation of new te hnologies, the design and programming of omplex appliations need to take into a ount standards and notions of ode distribution, deployment and reuse. There is a need to hange the programming methodologies to take into a ount these di erent fa ets. This paper lays the foundations for a new way of programming based on generative programming that automati ally integrates spe i te hnologies and user spe i ations (abstra t models). This idea was su essfully used, at di erent levels data representation, intera tive environments, semanti treatments and the ar hite ture, in the design and realisation of SmartTools, a software framework for domainspe i languages. In this way, the generated sour e ode makes use of XML te hnologies for the data representation, obje t and bean te hnologies for the views and GUI, aspe toriented programming and visitor design pattern for semanti treatments and omponents to obtain an open ar hite ture and a deployable distributed appli ation. This idea is very lose to the MDA (Model-Driven Ar hite ture) approa h of the OMG onsortium that advo ates a platformindependent model that an be transformed into one or more platform-spe i models. The main results of this new way of programming is better software quality due to business logi and te hnology separation, more straightforward ode, a rapid addition of new fa ets and a means that fa ilitates the portability of appliations towards new te hnologies or platforms.
