Examples
- In this paper , a concept for internet data exchang among hetergeneous databases system using xml middleware is proposed
本文提出了一个基于xml中间件技术实现异构数据库系统之间信息交换的模型。 - Through xml interface offered to the current different database system in business websites , the visit to databases in any platform can be implemented . with the help of xml , the visit result can be put out to other platforms in the form of xml and the information exchange is implemented among hetergeneous databases
通过为各商务网站现有的不同数据库系统提供一个xml接口,外界就可以借助xml实现对任何平台下的现有数据库的访问,并将访问结果以xml的形式输出到其它平台,从而实现了异构数据库间的信息交换。 - There are six chapters in this paper . the concept of hetergensous databases and the importance of data exchange among hetergeneous databases are illustrated in the first chapter . the adopted technology of hetergeneous databases exchange is introduced in the second chapter . and the idea exploring xml implementing hetergeneous databases exchange is proposed . the development of xml and its application are reviewed and the relation of the logical structure of xml and dtd and schema is analyzed in the third chapter . the structure of the system exploring middleware tecknology implementing data exchange among hetergeneous databases is investigated in the fifth chapter . conclusion is given in the sisth chapter as a summary for this paper
全文共分六章:第一章阐述了异构数据库的概念以及异构数据库间数据交换的重要性;第二章介绍了通常情况下异构数据库间数据交换所采用的各种技术,在此基础上提出了利用xml实现异构数据库间数据交换的思想;第三章回顾了xml的发展历程和其主要应用领域,分析了xml的逻辑构成以及dtd和schema的关系;第四章介绍了xml数据库的基本概念和相关技术并对其使用方法进行了分析;第五章介绍了利用xml中间件技术实现异构数据库间数据交换时的系统结构以及中间件的实现;第六章对全文进行了总结。 - In the prototype , a middleware using xml technology is constructed between the client ( or browse ) and database server , the communication between database server and the middleware is based on the xml information and interface . by means of the jdbc interface , we can transporently access hetergeneous databases system . and using xml information that is expressed in a structure , text - based format , we can describe the database information more accuratetly in a general format . at the same time , in order to describe the structure of xml files more clearly , the transpormation from schema has been realized
该模型在客户端(或浏览器方)和数据库服务器间利用xml技术构建了一中间件,在此模型中,中间件和数据库服务器之间的通讯是建立在xml信息和jdbc接口之上的。通过jdbc ,可以透明地访问异构数据库;借助于基于文本的结构化的xml信息,可以更精确地以一种通用的语言来描述数据库信息。同时,为了更精确地描述xml文件自身结构信息,实现了从dtd到xmlschema的转换。
