XML物化视图远程增量维护在试验任务数据接口同步中的应用

摘要

在试验任务中引入 XML 文档数据接口，一方面提高了远程数据查询分析的效率，另一方面也产生了XML物化视图的维护带来的高系统开销的问题。针对该问题，采用XML物化视图远程增量维护的方法，通过系统原型设计、系统部署、同步机制，可有效地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有效地实现了指挥显示系统数据接口的一致性。%XML data interface in the experiment task, on the one hand,not only improves the efficiency in the web data inquiry and analysis, on the other hand has also brought us the problem of the high cost of the system resource from the the maintenance of the XML materialized views. To resolve this problem, XML materialized views web incremental maintenance methods applied, through prototype system design, system deployment, synchronization mechanism,can effectively achieve the data interface synchronization of experiment tasks. The results show that, web incremental maintainenance based on XML materialized view effectively realizes the command display system data interface consistency in the condition of not affect experiment task data processing and transmission of real-time and reliability conditions.
