Integrated Data Management for Mobile Services in the Real World Christian Hage, Christian S. Jensen, Torben B. Pedersen, Laurynas Speicys, and Igor Timko   View Paper (PDF)   Return to XML & Mobility (Session C7) Abstract Market research companies predict a huge mar- ket for services to be delivered to mobile users. Services include route guidance, point-of-interest search, metering services such as road pricing and parking payment, traffic monitoring, etc. We be- lieve that no single such service will be the killer service, but that suites of integrated services are called for. Such integrated services reuse in- tegrated content obtained from multiple content providers. This paper describes concepts and techniques un- derlying the data management system deployed by a Danish mobile content integrator. While geo- referencing of content is important, it is even more important to relate content to the transportation in- frastructure. The data management system thus re- lies on several sophisticated, integrated representa- tions of the infrastructure, each of which supports its own kind of use. The paper covers data model- ing, querying, and update, as well as the applica- tions using the system. ©2004 Association for Computing Machinery
