摘要
为有效保证客户端物化视图与数据源的一致性并降低网络开销,提出一种物化视图增量维护方法。采用XML物化视图远程增量维护方法,通过系统原型设计、系统部署、同步机制,实现试验任务数据接口同步。结果表明:在不影响试验任务数据处理与传输的实时性及可靠性的条件下,XML物化视图远程增量维护系统可有效实现指挥显示系统数据接口的一致性、可靠性和安全性。
To ensure the materialized views on the Client Sldes consistent With tne data source and reduce the network cost, a kind of incremental materialized view maintenance method is put forwards. Using the XML materialized view web increment maintenance method, through the system prototype design, system deployment and synchronization mechanism, the experiment task data interface synchronization can be realized. The results show that, in the condition of not affecting the real-time performance and the reliability of the experiment data processing and transmitting, XML materialized view web incremental maintenance system can effectively achieve the command and display system data interface＇s consistency, reliability and security.
