Abstract

　取得部（６０１）は、発注データベースに形成された正区画ごとに、未完了トランザクション数を取得する。決定部（６０２）は、取得された未完了トランザクション数に基づいて、区画整理対象とする正区画を決定する。判断部（６０３）は、区画整理対象として決定された正区画に格納されているトランザクションごとに、未完了トランザクションか否かを判断する。格納部（６０４）は、未完了トランザクションであると判断されたトランザクションを予備区画に格納し、未完了トランザクションではないと判断されたトランザクションを別の記録媒体へ格納する。区画変更部（６０５）は、予備区画を正区画に変更し、区画整理対象として決定された正区画の両方を初期化して、このうちの一方を予備の区画に変更する。更新部（６０６）は、更新データを取得し、取得した前記更新データを用いて、予備の区画に格納された未完了トランザクションを更新する。
