However, it is hard to know future data accesses in each site. Moreover, frequently accessed data in each site may change as time goes by. Therefore, it is difficult to determine the optimal data allocation statically. In this paper, we propose the dynamic data allocation in distributed databasa systems to suppress the communication cost. In order to evaluate usefulness of the proposed method, we compared the communication cost of it with that of an usual caching method through simulations. In addition, we examined how to introduce the multiversion concurrency control to suppress the communication cost by avoiding abortion of transactions.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"72","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告マルチメディア通信と分散処理（DPS）"}],"bibliographicPageStart":"67","bibliographicIssueDates":{"bibliographicIssueDate":"1999-01-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4(1998-DPS-091)","bibliographicVolumeNumber":"1999"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
