Abstract: A continuous dynamic mobile query system including a mobile device is disclosed. The mobile device includes a mobile device memory, a query stored in the mobile device memory, a transmitter for continuously transmitting the query, a receiver for receiving a response, a mobile device output device for displaying the response. The system also includes a location source device for providing the location of the mobile device and a network adapted to receive the query and the location of the mobile device. The system also includes a database management system adapted to receive the query and the location of the mobile device from the network. The database management system is further adapted to execute the query taking into account the location of the mobile device to produce a response and provide the response to the network. The network is further adapted to receive the response from the database management system and transmit the response to the mobile device.

Abstract: Methods and apparatus for streaming data from a database system to a client system. In one implementation, a database management system includes: one or more data storage facilities for use in storing data composing records in tables of a database, where the data includes media data stored in one or more media objects; one or more processing modules configured to manage the data stored in the data-storage facilities; one or more quality of service modules configured to manage streaming media data from the data-storage facilities; and a database management component configured to receive stream requests and database queries for data stored in the data-storage facilities, including passing a stream request indicating media data to the processing module that corresponds to the data-storage facility storing the media data indicated by the stream request.
