          <datacite:description descriptionType="Other">これまでに、我々はデータベース構造劣化を低オーバーヘッドに測定する手法を構築し、構造劣化をリアルタイムに可視化できるオンライン構造モニタを提案した。当該モニタは管理者による構造劣化の分析及び再編成計画の作成に有用である。本稿では、再編成ポリシに従って構造劣化領域を同定するデータベース再編成支援機能を構築し、構造劣化モニタ上に実装した。</datacite:description>
          <datacite:description descriptionType="Other">So far, we made a method to measure structural deterioration of database with low overhad, and online structural deterioration monitor that can visualize structural deterioration in real time. The monitor is very useful for database administrator to analyze structural deterioration and create database reorganization plan. In this paper, we constructed an assistance function for database reorganization, which detects structurally-deteriorated portions following a given reorganization policy and implemented it into the monitor.</datacite:description>
