EXPedite: A system for encoded XML processing

Abstract

As XML becomes an increasingly popular format for information exchange, the efficient processing of broadcast XML data on a constrained device (for example, a cell phone or a PDA) becomes a critical task. In this paper we present the EXPedite system: a new model of data processing in an information exchange environment, which "migrates" the power of the data-sending server to receivers for efficient processing. It consists of a simple and general encoding scheme for servers, and streaming query processing algorithms on encoded XML stream for data receivers with constrained computing abilities. Experiments show the impressive performance of EXPedite. Copyright 2004 ACM.
