| Abstract: In order to solve the various existing problems in the distributed system,including multiple data sources,multiple heterogeneous databases,low resource efficiency exposed in the practical application of the database synchronization scheme,poor portability,and narrow application range,the paper analyzes the respective advantages and disadvantages of existing data synchronization techniques,puts forward a new database synchronization method with the combination of Sql plus and Merge statements,and designs the data synchronization system.Finally,the results of function comparison and performance analysis show that the scheme proposed in this paper is at a great advantage in several aspects,such as resource consumption,portability and application range. |
