摘要
分析了分布式数据同步的方法和策略,对SQL Server、Oracle等结构的数据库复制方案进行了对比,针对数据同步过程中对数据的一致性、安全性、高效性等需求,提出了采用二进制方法进行双向增量传输的数据同步方式,指出了异构数据库模式转换的要点。
With the application of data synchronization increasingly widespread, a detailed study of the methods and strategies of distributed data synchronization is made. A comparative study of the copy programmer of SQL Server, Oracle and other database is also made. The focus is on data consistency, security, high efficiency, and other needs in the process of data synchronization. A data synchronization method using binary incremental approach and two-way transmission is described. Some remarks about the conversion of heterogeneous database are also provided.
