Definition

Web Views are web pages or web page fragments that are automatically created from base data, which are typically stored in a database management system (DBMS).

Key Points

Although caching of HTML pages (and fragments) has been proposed in the literature as early as the mid-1990s, the term Web View was introduced in 1999 [2] to denote that these fragments are generated through queries made to a back-end DBMS.

The concept of a Web View facilitates the materialization of dynamically generated HTML fragments outside the DBMS. The main advantage of materializing Web Views (outside the DBMS, e.g., at the web server) is that the web server need not query the DBMS for every user request, thus greatly improving query response time for the user [3]. On the other hand, for the quality of the data returned to the user to be high, the system must keep materialized Web Views fresh (in the background). This essentially decouples the processing of queries...
