XML fragment caching for large-scale mobile commerce applications
Sebastian Obermeier, Stefan Böttcher · 2008
We present an XML data exchange technique suitable for mobile commerce systems involving thousands of mobile users and massive data loads. A key idea of our technique is that it is based on an XML information repository that is logically split into several disjoint data fragments. Thus, each mobile user's device can determine those parts of the information repository that are required for answering a given query locally at the device. The benefit of this local query processing is that our technique allows participating user devices to make their cached data fragments available to other participating devices and relieves the central information repository, resulting in a significant reduction of the overall data transfer and improved query response times.
