Abstract


Accompanied by the deepening of enterprise information work , you need to be broader geographically more dispersed range of enterprise information management system , the use of a distributed database system is the inevitable choice . In a distributed database system in order to improve the efficiency , reliability , and to reduce the burden on the network , often using data replication technology to save copies of the database at each node . Due to various limitations , slow network enterprise application network in particular, is an important form of remote network . Existing distributed database replication technology did not fully consider the characteristics of slow network bandwidth , reliability , and does not apply to a slow network environment . And the existing replication scheme is also a certain lack of flexible replication requirements to meet business users and supports heterogeneous database replication . In this paper, the characteristics of a slow network , proposed a solution to solve the slow network distributed bi-directional data replication problem . The program uses to adapt to the slow network environment \The program does not rely on a specific database , data transmission less network overhead , according to user needs flexible custom replication rules to adapt to the reliability of the network , robustness . This scheme has been applied to the enterprise database system solutions in a slow network environment , play practical utility .
