Xml-based Data Modeling And Data Exchange Technology

As the rapid development of the computer network technology and the extensive application of the Web technology, the.question of "information isolated island" becomes more and more serious.So, How to integrate and exchange the data which come from different platforms and departments has been one of the import research task of current information exchange.With its specialities of structured,extensible and independent of platforms,XML gradually becomes the technical standard exchanging data between applications and databases or different applications.This paper studied roundly the design and implement of a electronic document exchange system which transfered data by Message-Oriented Middleware and wrapped the data with XML.Besides,it studied the XML and Message-Oriented Middleware technologies used in the system.Using MQ to transfer data, this system can leave out the trouble of the rock-bottem communications as well as resolve the questions about security and asynchronism.On the other hand,it made the data have stronger structure and readability and also made it more convenient to communicate with differents of interfaces by using XML to wrap the data.In part of system design and implement, this paper first described the general design of the electronic document exchange and also discussed the structure and functional groupware of the data exchange platform and its sub systems. Second, it discussed the method of modeling XML Schema with UML and implemented modeling XML Schema of the XML documents exchanged in the electronic document exchanged system. At last, it decribed in detail the design and key section implement of the electronic document exchange system.
