Design and maintenance of data-intensive web sites
A methodology for designing and maintaining large Web sites is introduced. It would be especially useful if data to be published in the site are managed using a DBMS. The design process is composed of two intertwined activities: database design and hypertext design. Each of these is further divided in a conceptual phase and a logical phase, based on specific data models, proposed in our project. The methodology strongly supports site maintenance: in fact, the various models provide a concise description of the site structure; they allow to reason about the overall organization of pages in the site and possibly to restructure it.
