An Efficient Presentation-Architecture for Personalized Content.
Paul Libbrecht, Carsten Ullrich, Stefan Winterstein · 2003
A possible approach for generating personalized web-sites is to compose a page out of individual elements, for instance XML-fragments, and to transform the page to the desired output format, for instance HTML. However, the required transformation processes put a heavy load on the server, hence slowing down response times significantly. This article describes the architecture we developed to solve the performance problems that arouse out of the page generation process. In this architecture, the generation process is divided into several layers, with each layer adding/transforming wellspecified data. Among other advantages, this approach allows caching of individual transformed fragments. First results confirm that in this way the performance problems can be reduced. 1
