Abstract (in Japanese) (See Japanese page) 
(in English) RFID technology and sensor network systems produce huge amount of data, and stream data processing, which continuously processes the data in the real-time fashion, has proposed and accepted as a new data processing paradigm. For post hoc analysis or logging, database (DB) archive is required because stream data processing system disposes used data. However, archive processing throughput is low because DB archive contains disk I/O, and real-time data processing throughput is reduced by DB archive. This paper proposes two faster archive method, Asynchronous Bulk Store method and Archive-buffer-Synchronous Bulk Store method. The latter method can guarantee processing data are output after they are archived to DB. The result of evaluation in the prototype system shows throughput drop within 5.4% compared to No-Archive, and latency is within 200 milli-seconds unless real-time data processing throughput exceeds max DB archive throughput. Moreover, proposed archive methods are of advantage in smart-shelf system which is one of RFID applications.
