面向对象的多数据库系统中语义冲突分类框架

The Framework for Classifying Semantic Confilicrs in Object-Oriented Multidatabase Systems

<正>多数据库系统中模式集成是关键性问题之一。模式棠成一般包括~[1,2]：(1)视图集成,产生一个全局统一的概念模式；(2)数据库集成,将若干个已存在的数据库模式集成为一个全局模式,它是被集成库模式的一个虚拟视图。

This paper presents a three-layer framework for classifying semantic conflicts in object-oriented multidatabase systems, namely schema structural layer semantic conflicts, object-instance layer ones, and behavior-method layer ones. The corresponding resolution to these conflicts are also suggested in this paper.
