Abstract
A materialized hypertext view is a hypertext containing data coming from a database and whose pages are stored in files. A Web site presenting data coming from a database is an example of such a view, where the hypertext pages are HTML files. Even if the most popular approach to the generation of such sites is the virtual one, there is also a rationale for a materialized apporach. This paper deals with the maintenance issues required by these derived hypertext to enforce consistency between page content and database state
