Publish Technical Studies, Database Sharing Of Xml-based Network Environment

With the development of Information Techonology,especially the popularizing of internet,the obturate of DataBases of institutions with pivotal canonical information turns to a serious problem. This encumbers the development of information tech effectively using of information and consistency of especially information between institutions. Consequently,In this article,We propose a series of solutions of Databases sharing and integration under internet.The solutions are composed of four parts:releasing of DataBase profile Description of sharing requirement releasing of requirement distilling and integration of information. By summing up the research of relate techonology,We focus our research on the Description pattern of sharing requirement and exchange protocal.We propose the idea of E-R Description pattern of requirement. On the same time,by analysised the characteristic of XML,We use XML to build the protocal of data sharing and integration.For expansibility,we achieve all the idea based on Java.To be concluded,the main work done are:Propose solutions of Databases sharing and integration based on XML;Describe and release DataBase profile by XML;Propose the idea of semantic E-R Description pattern of requirement;Propose the model of commen SQL syntax verifing;Research the strategy of security in DataBase sharing and integration.
