摘要

Whenever a restricted bandwidth is the bottleneck of an application that transfers data from a server hosting a huge XML document to a client with limited resources, there exist mainly two approaches to overcome this problem: caching previously downloaded data on the one hand, and transferring compressed data on the other hand. We present a combined approach that combines both approaches, i.e., that proposes a caching framework working with compressed XML data. Our performance evaluation demonstrates that this combination not only yields a benefit in terms of the data to be transferred, but it also yields a shorter response time for queries to be evaluated on the client. The benefit reached by the combination of caching and compression is even stronger than the sum of the benefits reached by each of these techniques alone.
