Return to Location-based services and mobile computing: data models With the recent and continuing advances in areas such as wireless communications and positioning technologies, mobile, location-based services are becoming possible. % Such services deliver loca\-tion-dependent content to their users. More specifically, these services may capture the movements of their users in multidimensional databases, and their delivery of content in response to user requests may be based on the issuing of complex, multidimensional queries. The application of multidimensional technology in this and other contexts poses a range of new challenges. This paper aims to provide an appropriate multidimensional data model. In particular, the paper extends an existing multidimensional data model to accommodate spatial values that exhibit partial containment relationships instead of the total containment relationships normally assumed in multidimensional data models. ![]() DiSC'03 © 2003 Association for Computing Machinery |
