摘要
随着物联网技术的快速发展,网络中存在大量的异构数据库,其异构性表现在多个方面。当数据库模式不同时,产生的数据类型也不尽相同,为保证数据的一致性,研究基于DM2的异构数据一致性校验方法。在异构系统中捕获异构数据包,通过良性和恶意线程运行模式,分析异构数据的特点。划分异构数据类型,处理并计算数据值。基于DM2技术构建输出图,设定一致性校验原则。以校验原则为基础,构建一致性验证矩阵,实现异构数据的一致性校验。实验结果表明:在不同数据源的并发过程中,所提方法能够有效召回错误数据记录,且召回正确率均在95%以上,具有较好的应用效果。
With the rapid development of Internet of Things technology,there are a large number of heterogeneous databases in the network,and their heterogeneity is manifested in many aspects.When the database models are different,the data types produced are also different.To ensure the consistency of data,an automatic consistency verification method for heterogeneous data based on DM2 is studied.It captures heterogeneous data packets in heterogeneous systems,and analyze the characteristics of heterogeneous data through benign and malicious thread running modes,it also divides heterogeneous data types,processes and calculate data values,builds the output map based on DM2 technology and sets the consistency verification principle.Based on the verification princi-ple,a consistency verification matrix is constructed to verify the consistency of heterogeneous data.The experimental results show that in the concurrent process of different data sources,this method can effectively recall the wrong data records,and the re-call accuracy is above 95%,which has good application effect.
