Context-Sensitive Compression of Database Updates for Wireless Transmission

Abstract

This report presents ways of encoding database to database updates (DDUs) to minimize communications bandwidth. The methods discussed are flexible and more easily extended than bit oriented protocols (BOPs). The strengths and weaknesses of DDUs and BOPs are discussed. Typical DDUs are shown and the various data types sent in messages are explained. An analysis is performed to empirically determine the savings obtained by using the encoding methods. Finally, a decoder that generates structured query language (SQL) DDUs is presented as an example of the applicability of the algorithms to act as DDU translators.
