Stream data processing, which continuously processes the data in the real-time fashion, has proposed and accepted as a new data processing paradigm. Data lifetime notion is essential in the stream data processing because it requires extracting the target data from infinite data sequences using the notion. Negative Tuple Method (NT) and Direct Method (DT) have been proposed to manage the data lifetime. Although DT outperforms NT in the system throughput, it cannot be applied to some basic query processing operators due to its processing mechanism. This paper proposes a new data lifetime management method which extends DT to enable applying it to the basic query processing operators as the same as NT. Moreover, we have confirmed by experiments that our new data lifetime management method outperforms NT by 1.4-2.0 times in the system throughput.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"276","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告データベースシステム(DBS)"}],"bibliographicPageStart":"269","bibliographicIssueDates":{"bibliographicIssueDate":"2006-07-13","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"78(2006-DBS-140)","bibliographicVolumeNumber":"2006"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"links":{},"id":18918,"updated":"2025-01-22T22:29:58.023243+00:00"}
