Integrated Data Management for Mobile Services in the Real World C. Hage C. S. Jensen T. B. Pedersen L. Speicys I. Timko Euman A/S Vodroffsvej 7, DK-1900 Frederiksberg C Denmark ch@euman.com Department of Computer Science, Aalborg University Fredrik Bajers Vej 7E, DK-9220 Aalborg Ø Denmark csj, tbp, laurynas, timko @cs.auc.dk 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. 1 Introduction Strategy Analytics, a leader in providing strategic and tac- tical support for business planners, recently concluded that: “Demand for mobile information services is skyrocketing and interest in coupling them with positioning technologies [is] at an all time high.” A USD 9 billion and a USD 7 Permission to copy without fee all or part of this material is granted pro- vided that the copies are not made or distributed for direct commercial advantage, the VLDB copyright notice and the title of the publication and its date appear, and notice is given that copying is by permission of the Very Large Data Base Endowment.

Proceedings of the 29th VLDB Conference, Berlin, Germany, 2003 billion annual revenue opportunity from location-based ser- vices is foreseen by 2005 in Western Europe and the USA, respectively [15]. Strategy Analytics expect that location technologies will augment existing wireless data applica- tions as well as spawn a host of entirely new services, in- cluding alerts and ads, and personal location and guidance services. The mobile services value chain involves a range of dif- ferent services, including at least content provision, con- tent integration, service development, service hosting, wire- less communication provision, and billing. Following the maxim that “content is king,” we believe that the integration of content and the reuse of content across multiple services will be central to the cost-effective delivery of competitive mobile services as well as to the rapid development of new mobile services. Consequently, we see content integration
