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.
