Nowadays a considerable amount of web sites are data-intensive web sites, meaning that web pages are generated by extracting their content on the fly from a database system. Systems of this type are often the result of an integration process between intranet legacy systems and Internet web applications that represent the front end of the organization towards the rest of the world. The globalization process, that influences the activities of any organization (company, public agencies, etc.), makes it necessary to provide information in different languages in order to enlarge the audience of the information presented through the web. Therefore, it is often required to extend the web system for handling information in more than one language. This process is called internationalization of an application or system. Another important requirement in this process is that it should be applied without a strong reorganization of the web applications that implements the web site, so that the main cost would regard the translation of the web contents. We propose a general framework for the internationalization of data-intensive web application based on the MVC-2 paradigm and a relational database system. Moreover it can be applied to existing web applications with a low impact on code restructuring. This framework has been applied at the University of Verona (Italy) for the internationalization of the web sites of all departments and faculties of this university.
