NF2的扩展与NF2多媒体数据模型的设计与组织方法

The Design and Organization for the NF2 Multimedia Data Model Based on the Extension of Non First Normal Form

    摘要
  • 摘要: 分析了多媒体空间数据模型的特点,基于关系数据库理论,提出了一种组织和存储多媒体空间数据的有效模型──NF2的多媒体数据模型,它是传统关系模型的扩展。借助于这种数据模型,能够有效地存储图像、声音、视频等多媒体空间数据,并且允许关系的属性是另外一个关系,从而解决了多媒体系统中的嵌套结构功能。

     

    Abstract: In this paper, the characteristics of the multimedia data model has been analyzed.One model for the organization and storing multimedia data, namely the multimedia data model based on the non first normal form (NF2) has been proposed based on the theory of relation database and extension for the non first normal form. With the help of this model, the multimedia data such as image, sound, video and so forth and embedding structure of multimedia data can be effectively stored and managed.
