We applied the multidimentional data management structure, named BD-tree, to geometrical database management. In the beginning we made two management struc-ture, named the layer BD-tree and the unification BD-tree. The former manages all data under one BD-tree and the latter manages each data under each BD-tree divided by the kind of data. We examined three basic retrieval, are range-retrieval, most-nearest-retrieval and combination-retrieval, on these data management structures.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長野工業高等專門学校"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00179170","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-1909","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"宮崎, 敬"}],"nameIdentifiers":[{"nameIdentifier":"1385","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-02-21"}],"displaytype":"detail","filename":"nagano_nct-19-10.pdf","filesize":[{"value":"432.5 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"nagano_nct-19-10.pdf","url":"https://nagano-nct.repo.nii.ac.jp/record/654/files/nagano_nct-19-10.pdf"},"version_id":"b28ebab3-0bda-4de8-8ae2-a8775f7f0cdd"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"図形管理におけるBD木の性能評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"図形管理におけるBD木の性能評価"}]},"item_type_id":"2","owner":"17","path":["41"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-02-21"},"publish_date":"2013-02-21","publish_status":"0","recid":"654","relation_version_is_last":true,"title":["図形管理におけるBD木の性能評価"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-20T15:59:27.521419+00:00"}
