Research And Implementation Of Data Synchronization Based On JMS

With the development of information technology, computer was widely used,enterprise managers gradually realized great effect of the comput er informationtechnology as a tool of data processing, had the construction of enterprise informationsystem, and even the same enterprise in different regions of the Department alsoconstruction department information system, these systems were provided by differentsoftware vendors, databases and development the platform employs different,resulting in data of the enterprise information system was isolated, as one of"information isolated island", Enterprise data could not form a true sharing. In orderto make between these departments and subsystem realized data sharing, datasynchronization technology use was essential.This paper analysised on the mainstream database data synchronization toolmanufacturers, the third party Data Processing Inc data synchronization technologyand other synchronization technology research program, summed up the advantages ofsynchronous tools and techniques, but also found limitations of these tools boxtechnology, and makes a comprehensive comparison. Then according to th e morecomplex application system of environmental requirements, in-depth study of the Javamessage service (Java Message Service, JMS) technology, combined with thepublish/subscribe and point to point two messaging model, proposed a JMSarchitecture of the information service model based on the JMS (JAVA messageservice) technology to achieve data synchronization and data synchronizationalgorithm. This paper was the operation of electronic commerce project " B2C " of thedata synchronization based on the background of the implementation of complete. Inthe system requirements analysis combined with e-commerce, the design of a JMSfrom the bidirectional data online mall MYSQL database to ERP databasesynchronization scheme based on Oracle system. According to the text andplatform-independent characteristics of XML, using XML as the intermediary textMYSQL database and Oracle database, fully meet and cross-platform heterogeneousdata sources are needed. Verified by the project implementation and, based on JMS(JAVA message service) data synchronization technology for efficient processing ofdata between online shopping mall and ERP system under the condition of highconcurrent synchronization and maintain the correctness and high stability to play a key role. And since the synchronization process and system functions to read andwrite is relatively independent, and do not influence each other, but also greatlyreduce system database read and write pressure.Data synchronization scheme(algorithm) in the paper had several innovations,support structure and heterogeneous database system; provided the interface couldeasily be configured system data synchronization between configuration, and datasynchronization; massive data and high concurrent data synchronization;synchronization mode supports instant, timing, manual mode, the user canindependently choose according to the need of the system; Data synchronizationalgorithm to ensure the data validity, integrity, resource consumption of small, highefficiency of data synchronization stability, good compatibility;stability construct avariety of exception handling mechanism to improve the data synchronization processand correct. The paper analyzes the problems existing in the system, in order to solvethese problems and put forward the future research work focus and prospect for thefuture.
