A Method for the Logical Design of the Hierarchical Data Model

概要

論文の詳細を見る
A logical database design generally consists of two stages: designing the conceptual schema, and translating it into object data models acceptable by the underlying database systems. In this paper, the Entity-Relationship model is used to describe the conceptual schema, and the translation process from the Entity-Relationship model to the hierarchical model is proposed. In the trarlslation process, the existence dependencies and the hierarchical decompositions which represent the inherent hierarchical properties of information are analyzed. The query characteristics are also investigated and formulated in the form of the access weight matrix.
