Dynamic Web View Materialization

Abstract

Dynamic Web applications, such as e-commerce Web application, extensively use databases as backend servers. These Web applications are highly dependent on the efficiency with which the Web databases can be accessed. A dynamic Web page consists of many small fragments of scripting languages, called Web views, which may require access to data in disparate databases. These Web views when materialized can enhance the efficiency of database access. An e-commerce Web application has large number of users involved in various personalized interactive activities. These generate a stream of Web page accesses and modification requests that necessitate taking dynamic decisions for selecting Web views for materialization, which minimize the average access time of Web views. In this paper, a Web view selection algorithm (WVSA) that selects Web views for materialization is proposed. Experimental results suggest that materializing Web views using WVSA increases the efficiency of Web view accesses.
