本研究では，系図表示ソフトウエアにおいて各個性の関係性を容易にハンドリング可能な新しいデータ管理手法Widespread Hands to InTErconnect BASic Elements (略称WHIteBasE) を提案する．WHIteBasEは基本的に，婚姻関係と子の発生を1つのイベントとして統合管理するための不可視結節点である．即ち，個性データは直接他の個性データからは一切参照されず，WHIteBasEからのみ参照される．その結果，データベース容量が少なくなるだけでなく，複雑な婚姻形態の表示や線分交叉の探索も容易になる．本手法をプロトタイプソフトウエア上に実装し，その有効性を検証した．In this paper, we propose a new data management method for handling relations on genealogy display software easily. It is named "Widespread Hands to InTErconnect BASic Elements (WHIteBasE)". The WHIteBasE is a hidden node for integrating the relations due to an event including a married couple and their children. That is, individual's data does not refer to others directly, and only refers to WHIteBasEs. As a result, the number of references is less than the existing data structure. Therefore, the volume of database is smaller, the complex multiple marriages can be set easily, and the positions of the segment intersections can also be searched easily. Our new prototype software and the effectiveness of our method are shown.
