用对象—关系数据模型进行多媒体数据建模

On Constituting Data Model in Multimedia Database with Object-Relation Method

通过对现今常用的超媒体技术、面向对象技术、扩展的关系模型技术等 3种多媒体数据建模技术进行分析比较 ,提出用对象—关系建模技术进行多媒体数据建模 ,以及实现从面向对象模型到关系模型转换的算法 ,并用实例演示了这一过程 .

After analyzing three kinds of technologies-hypermedia technology, object oriented technology, NF2, this paper gives a kind of data model method-object relation data model and an algorithm which can change object data model into relation data model.Finally, some examples of application with this method are given in this paper.
