This multimedia engine is separate from database system , can be exploited , installed and applied independently on most database release , it make the relational database management system can support management and content - based retrieval of multimedia data 多媒体数据库引擎从数据库系统中分离出来，它能被开发、安装和独立地应用在所有发行的大型关系型数据库产品中，使现有的关系型数据库管理系统能够支持时多媒体数据的管理及基于内容的检索。
In order to solve the problem of medical data storage properly , after studying deeply on multimedia database system , we give the method of constructing medical multimedia database system not only based on traditional rdbs but also on oodbs in a creative way 为了解决数据存储的问题，作者在深入研究了多媒体数据库技术后，除了实现在传统的关系数据库上构造医学多媒体数据库之外，还提出了基于面向对象数据库技术构造医学多媒体数据库的设计方案。
The original knowledge which is described in natural language in electronic text is disposed by filtrating , semantic block segmenting , word segmenting , syntax and semantic analyzing , pattern matching . in the end it is expressed in the semantic network and storaged in the multimedia knowledge database 在本系统中,原始的以电子文本形式存在的自然语言描述的知识经过过滤,切分语义块,分词及语法、语义分析,模式匹配,以语义网络的形式存入多媒体数据库。
This is the article third part . this article fourth part is to the platform system technical implementation research . this part first introduced the multimedia database implementation principle and the technology , then introduced controls the platform the implementation technology , the key elaboration middleware design , the 这一部分首先介绍了多媒体数据库的实现原理和技术，然后介绍了管理平台的实现技术，重点论述中间件的设计和动态网页数据库asp技术，详细讨论了asp的主要功能及对资源库的操作实现技术，并对网页合成技术做了简要介绍。
By using computer network , distributed multimedia database , speech signal process and computer graphics technologies , this project use non - diving into virtual reality technology to implement virtual radio detection work environment through the simulation of electromagnetic environment , receiver and recorder among radio detection work to make those who take part in training immerse in similar training environment as real detection work and achieve the same training effect as in real detection work 本课题采用计算机网络、分布式多媒体数据库、语音信号处理和计算机图形学等技术，运用“非投入”式虚拟现实技术方法，通过对无线电监测工作中电磁环境、接收机和录音机的仿真，实现了无线电监测人员工作环境的虚拟，从而使参训人员投入到与监测工作实际相近的训练环境、达到与实际监测工作相同的训练效果。
So i can use the common way of relational database to retrieve the multi - data , which can be accomplished by using basic function of pb6 . 5 . to delete multi - data , i should delete the whole data item , which also can be accomplished by using the basic function of pb6 . 5 . i need to solve how to insert multi - data and which kind of forms to display in front of client 解决检索问题，是利用给予多媒体数据的关系型数据的描述，将关系型描述存入到多媒体数据库中，利用关系型数据库的检索方法来实现对多媒体数据的检索，这一点只需要利用pb6 . 5的基本功能就可以实现；解决删除问题，是利用在各种类型的数据库中删除一个数据项通常不用去关心数据项的具体内容，也就是不关心数据项的类型，而进行删除，所以对于多媒体数据库系统中数据的删除也可利用pb6 . 5的基本功能实现。
