| 520 | _aRecent advances in positioning technologies and wireless communications lead to a proliferation of location-based services. The moving-object database is a specialized database system for e{uFB03}ciently storing and processing the location data in location-based services. The dynamic nature of objects introduces new challenges to existing database techniques, especially dealing with the frequent location updates. Given the massive number of GPS-equipped mobile devices and the spectacular growth rate today, it is of vital importance to consistently improve the performance of moving-object databases.The problem of moving-object management has attracted great attention from the researchers. For a long time, researchers want to enhance the performance of the database system, as the traditional databases are designed for static objects, for which updates are infrequent. Moving-object databases, on the other hand, are proposed specially for managing moving objects, whose locations change frequently over time. To track the objects continuously, objects are required to inform the system about the changes of their locations, resulting a huge updating workload to the database system. The high frequency of updates on the data is a unique feature that di{uFB00}erentiates the moving-object database from traditional databases | ||
