摘要
在稳定性不好的网络环境下利用SQL server数据库的复制功能进行数据同步容易造成数据的不一致性。本文研究了一个基于SQL server复制方法和压缩技术的数据库同步软件DataSend的设计与应用。DataSend通过建设中间层缓解了源数据库和目标数据库的压力,对传输数据进行压缩处理后再传输;通过状态来控制传输的准确性,从而提高了数据同步的传输效率、灵活性、安全性和准确性。
In the instability of network environment, data in phase through the use of SQL Sever database＇s copy function will lead to the inconsistency of data. This paper discusses about the design and application of database in phase sottware- DataSend which is based on SQL Sever copy method and compress technique. DataSend abates the pressure of source database and destination database by build the mesosphere, tranmits again after compress the TD, controls the veracity of transmission through state, improves the data inphase of transmission efficiency, flexibility, security and veracity.
