| Earth because the development of network technology becomes a village, mensince the development of data storage technologies and become more intelligent. Isinevitably in the future information society, people receive large amounts of data eachday, at the same time also spent in anxiety and fear, because of the lack of integrationof information, screening and refining. Appearance of database technology for humansolved the problem of a large number of database storage, birth database technologyfrom the outset is not perfect, however, needs to be further developed. Meanwhile,huge amounts of data but also to teach us that some kind of nature, waiting to bediscovered. However, the current limited use of data, and analyze data on a globalscale Super calculations are still not available. Future data storage still has a long wayto go, workers remained in first-line of the database are struggling at home andabroad.In other countries, many large companies have invested a lot of manpower andmaterial resources for database synchronization technology innovation anddevelopment. On top of data synchronization, mainstream database ORACLE andIBM have their own data synchronization system. At home, the late information ofcompanies and social organizations in China, the degree and level than abroad, is in astate of long-term catch-up.But with the development of globalization across units, interdisciplinary andmultidisciplinary analysis of the data has become increasingly important. Data sharingbetween databases will greatly promote the utilization rate of resources, so as topromote the development of innovation capability, and providing new growth enginefor China’s economic development. At present, data synchronization features inexisting database product in order to have an effect, but its multifunctional adaptationabove also does not meet the user’s criteria. As well as technical, geographicalconstraints caused stagnation in database technology. In order to meet the needs ofreal life, into an increasing number of experts and scholars in the development and application of database synchronization technology. Database synchronizationtechnology, particularly with respect to different synchronization technologies,scramble will be the future of computer data storage industry for vantage point. Thisis the background of this article.Main content of the article is based on the J2EE platform, data synchronizationsystems development using Spring MVC pattern. This system is mainly extractedfrom the database is to facilitate customer part or all of the data from one environmentto another environment, while reducing the customer’s data synchronization mayappear unnecessary work. Using the MVC framework, you can reduce the coupling,and then encapsulates the business logic layer for data, and further distinguish the datastorage layer for future maintenance. In literature as well as in the previous section ofthe article needs to Spring MVC model based on your analysis of datasynchronization system is designed, the latter part is the implementation and testing ofthe system. The feasibility of this process is in line with the process of databasedevelopment, security and development principles.System of main function including customer information management, usermanagement, storage management, scheduled management, and data synchronization,through on database of operation management user of information, and storage andscheduled of management is is used dom4j on since defines of XML file forcorresponding of deletions modified check, through storage, and scheduled of selectand set, achieved will database in the a Zhang table in the of part field or all fieldsynchronization to another a Zhang table in the, that ISO library synchronization,while achieved ISO table structure synchronization. While the synchronization of databetween databases on different database performance will pick up above, datasynchronization between heterogeneous databases is the highlight of the article. |
