ABSTRACT:
A stream data processing system capable of highly reliable and highly usable real time data processing, is provided with: (1) a mechanism of copying some or all of stream data, and archiving the stream data in a non-volatile memory to allow real time data and archive data to be used seamlessly; and (2) a mechanism of improving the performance of query processings by using a plurality of stream data processing systems cooperatively.
