XML And JMS-based Synchronization Of Heterogeneous Databases

As the deepening of the enterprise' automation and information, between various departments of enterprises goes more frequently. The dilemma we are facing is that as the information process is not synchronized, the data exchange between different enterprises will produce the phenomenon of heterogeneous synchronization and the problem of how to exchange data effectively between heterogeneous information systems and how to share the exchange of data in heterogeneous systems and other issues.This paper takes the data exchange and data sharing as the main issues. Based on the deep study of XML and JMS technology, the paper uses the communication mode of JMS to exchange data, uses the superiority of XML documents to transform the exchange data into the XML document form, and exchange data between heterogeneous systems on the JMS server. Also, this paper designs a new data exchange model, and gives detailed solutions of the data synchronization between heterogeneous systems.Here are the major work and the achievement of the paper:(1)For the current enterprise information construction process, the heterogeneous environment of data exchange are the major issues.This paper introduces the major solutions and the related theory of the data echange among the current information system in detail.(2)Some details about the XML standard and its open-system programming interface,,JMS application architecture,JMS messaging component and JMS programming model.(3)Though the study of the XML technology, middleware and data synchronization system architecture,people have designed a information exchange model based on JMS. The model maps the relationship of data structure in the data source to the XML document structure. That is to use XML as a intermediate data format to achieve data conversion in data source of heterogeneous system, how to publish XML documents to the JMS server, and use JMS to deal with the problem of data exchange and data synchronization between heterogeneous systems. The model includes two core components:XML message service components and data exchange tool.(4)Design the solutions based on XML and JMS overall heterogeneous data synchronally. There are two major problems in the component's implementation: how to achieve distributed applications based on JMS messaging between systems, and how to achieve data conversion between practical applications of data sources and XML documents. This paper gives some practical examples of the model(5)This paper also brings forward the improvement works on the model from the practical and perfect direction.
