| Along with the development of enterprise informatization and wide use of network as well as computer, one of the most important issues to be considered in modern enterprise application system is how maintain data synchronization efficiently and safely among databases, which could not only enable the settlement of data processing within and among every department to ensure the sharing of information.The main topic of this paper is the transmission of distributed database synchronization technology. Database synchronization mechanism could resolve the coincidence of a number of lower-level database on the database information exchange process data and give solution to DDBS's data transmission sending and receiving database consistency and reliability of the transmission system.The way to ensure the coincidence of data dispatching and receiving are the synchronism analysing and studying distributed data base renews mechanism with probing the relevance technology; designing the compatibility transferring buffer pool , ensuring that sending data buffer pool and taking-over data buffer pool coincide to ensure that dispatching a data base and receiving a data base synchroly by the software engineering; Adopting data base daily record to renew a technology, transmission process is useful daily record transmission replace data transmission , lighten data loads , improve transmission efficiency. |
