Adapting Relational Database Engine to Accommodate Moving Objects in SpADE

In this work, we present our implementation for managing moving objects on top of a popular relational database system MySQL, namely SpADE (spatio-temporal autonomic database engine for managing moving objects). In our SpADE system, non-static entities like vehicles and pedestrians are abstracted as moving objects. They obtain positioning information with GPS (Global Positioning System) receivers installed, and are able to communicate via wireless network with the server, sending queries to and receiving results from it. The server is responsible for managing moving object information and processing queries from mobile users. By employing the industry standard JDBC for the data access, our server can also support providing services for other application interfaces such as the Web.
