基于XML的自动化异构系统数据一致性校验方法

XML based data consistency checking method for automated heterogeneous systems

针对异构数据一致性校验问题,提出基于XML工具的校验方法研究。分析了XML文档与异构数据库的数据映射关系,及数值转换关系,并构建异构数据一致性校验模型,分别校验副本数据和数据库表数据,分块计算差异数值,以提高总体异构数据的样本一致性。实验结果表明,提出的异构数据一致性校验方法在不同的网络延迟下数据恢复的耗时更低,数值波动的均值指标、方差指标相对于现有校验方法更有优势。

Aiming at the problem of consistency checking of heterogeneous data,this paper proposes a method of checking based on XML tools.This paper analyzes the data mapping value and transformation relationship between XML document and heterogeneous database,and constructs the heterogeneous data consistency verification function to verify the replica data and database table data respectively,and calculates the difference value in blocks to improve the sample consistency of the overall data.The experimental results show that the time-consuming of data recovery is lower under different network delays,and the mean and variance indexes of data fluctuation are better than the existing methods.
