On query processing for large-scale XML data, XML storage schemes on secondary storage and their access methods greatly affect the entire performance. For this reason, we developed an XQuery processing scheme in which XML data is internally represented as a set of DTM blocks, and can directly be stored on secondary storage. Moreover, we adapted the use of extents for queries whose locality of referred blocks is high, and introduced Reverse-Path index for queries whose locality of referred blocks is low. Our experimental results show that the proposed scheme can often obtain almost linear scalability in performance as the data size increases, and is especially adaptable to limited resource environments.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"148","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"128","bibliographicIssueDates":{"bibliographicIssueDate":"2007-06-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG11(TOD34)","bibliographicVolumeNumber":"48"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
