Description
A data modelbased on semantic data model which can treat set-valued functions is introduced,and path functional dependency for such data model is investigated. Also an effective algorithm of the closure calculation in the data model is proposed and considered.

意味データモデルにおける経路を集合値写像として与えることを提唱し,その経路関数従属性について考察する.また,このモデルでの閉包計算を効率よく行うアルゴリズムを提案し,その有効性について検討する.
