对象-关系超媒体数据模型的研究及应用

Principle, Method and Application of Object-Relation Hypermedia Data Model

在分析了NF2多媒体数据模型、面向对象的多媒体数据模型和超媒体数据模型的基础上 ,进一步提出了一种集上述三种模型优点的、能更有效地组织和管理多媒体信息的数据模型 ,即基于对象 -关系的超媒体数据模型 (Object-RelationHypermediaDataModel,O -RHDM)。论述了O -RHDM的基本原理、数学基础、组织和存储方法 ,并给出了具体的应用实例。

In this paper, one multimedia data model, namely Object-Relation Hypermedia Data Model (briefly O-RHDM) which is advanced and effective data model has been proposed and designed based on the analysis of the Non First Form (briefly NF2) multimedia data model, original-object multimedia data model and hyper media data model. Its principle, mathematical description, algebra operation, organization method and storage model are also discussed. The specific application example is given combining with the hainan multimedia touring information system.\;
