Study on multimedia database management system arclritecture

本课题的目的是提出一个多媒体数据库管理系统的体系结构。多媒体数据库是指将字母数字数据库、图形数据库、图像数据库、声音数据库等多种单一媒体数据库集成在一起，使用户在使用多媒体数据库时不受媒体差异的影响。虽然已经认识到这种数据库的必要性和重要性，但如何开发多媒体数据库及其管理系统还不清楚。本课题通过两年的研究，明确了以下几点：(1)媒体的定义、多媒体数据模型、多媒体数据库；(2)基于对象的集成方法构建多媒体数据库；(3)面向对象方法的本质必要性；(4)面向对象的通用多媒体数据库环境OMEGA的介绍；(5)对象概念、对象标识、对象基本操作。

The aim of this project is to present an architecture of multimedia database management system.By multimedia databases, we mean a database into which a variety of single media databases such as alpha-numeric databases, figure databases, image databases, and sound databases are integrated so that the users can use the multimedia database without awareing of the difference of media.Although it has been recognized the necessity and importance of such databases, it has been not clear how to develop multimedia databases and their management systems.We explored the topic or two years in this project and made it clear the following points:(1) Definition of media, multimedia data model, multimedia data base,(2) Object-referred integration method to build multimedia database,(3) Essential necessity of object-oriented approach,(4) Presentation of OMEGA (Object-oriented Multimedia database Evironment for General Application),(5) Object concept, object identity, and basic object manipulation.
