In this paper, we discuss the problem of processing aggregate queries on the location databases and propose the two step position locking protocol that can guarantee the queries to get the consistent results.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"46","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":"39","bibliographicIssueDates":{"bibliographicIssueDate":"1998-07-08","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"57(1998-DBS-116)","bibliographicVolumeNumber":"1998"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"updated":"2025-01-22T21:58:41.583479+00:00","created":"2025-01-18T22:52:13.679377+00:00","id":19884}
