Towards the Managment of Time in Data-Intensive Web Sites

The adoption of a logical model for temporal, data-intensive Web sites is proposed together with a methodology for the development. The model allows the definition of page-schemes with temporal aspects (which could be related to the page as a whole or to individual components of it). The design process follows a development that starts with a traditional E-R scheme; the various steps lead to a temporal E-R scheme, to a navigation scheme and finally to a T-ADM scheme. A tool associated with the methodology has been developed: it automatically generates both the relational database (with the temporal features needed) supporting the site and the actual Web pages, which can be dynamic (JSP) or static (plain HTML), or a combination thereof.
