Abstract: WebView materialization is an important method to improve the query response performance of a web server. As opposed to data warehouse in which updates are usually performed off-line, updates of materialized WebView need to be done online.However, there is little research on the issue.This paper gives a review and proposes an asynchronous and deferring update approach (ADUA), which is composed of synchronous inspection of materialized WebView update (SUIMW), deferring update of materialized WebView (DUMV) and asynchronous update of materialized WebView (AUMW).The approach combines asynchronous update and deferring updating to realize the freshness of materialized WebView efficiently, and can significantly accelerate response to queries.

Key words: WebView, materialization, update
