WebView Materialization

A WebView is a web page automatically created from base data typically stored in a DBMS. Given the multi-tiered architecture behind database-backed web servers, we have the option of materializing a WebView inside the DBMS, at the web server, or not at all, always computing it on the fly (virtual). Since WebViews must be up to date, materialized WebViews are immediately refreshed with every update on the base data. In this paper we compare the three materialization policies (materialized inside the DBMS, materialized at the web server and virtual) analytically, through a detailed cost model, and quantitatively, through extensive experiments on an implemented system. Our results indicate that materializing at the web server is a more scalable solution and can facilitate an order of magnitude more users than the virtual and materialized inside the DBMS policies, even under high update workloads.

The Common Gateway Interface (CGI) is a well-established flexible solution for extending an HTTP server functionality. Unfortunately, it has intrinsic problems with throughput and effective resource use. These shortcomings become particularly appreciable for the CGI scripts with advanced functionality. Thus, using

The interoperability of information systems has been pursued for a long time and is even more demanded in the Internet era. This paper reviews the literature in this area, from the database perspective. It covers work on interconnection of databases, classification of data integration problems, major standards and architectures, and the most recent developments in the fields of semantic Web, Web services and scientific workflows.
