IFO模型在数据库逻辑设计中的应用

Applying IFO Data Model in the LogicalDatabase Design

反映信息系统的结构语义是数据库设计的主要目的之一。这一目的一般采用语义数据模型来达到。我们考察这一问题的逆问题:识别关系数据库模式中IFO结构。本文描述了将无语义的关系模式转换成IFO图的方法,同时给出了该方法的具体应用。

One of the main goals of database design is to capture the structural semanticsof information systems. This goal can be achieved by using a semantic data model,In this paper, the reverse problem, identifying IFO object structures in relationalschemas in discussed. A method of mapping uninterpreted relation schemes intoIFO diagrams is described. Its practical applications are given.
