摘要
目前,企业数据往往分散于各个独立的业务系统中,因此不能很好的实现数据的统一管理和集成,基于对分布异构数据资源特点的分析,提出了一种保持数据完整性的数据集成机制.该机制通过三级模式(本地模式、局部模式和全局模式)的映射建立了层次化的数据模型,屏蔽了数据的异构性,并提出了一个数据完整性检查算法,即在数据集成中保证了基于全局模式的数据完整性,从而达到了既能实现数据资源的共享,又能将分布异构的数据资源形成有机整体的目的,最后以地震行业前兆数据集成平台的某一应用场景为例,说明了该数据集成机制具有保持数据完整性的能力.
At present, the enterprise data is often scattered in various independent business systems, therefore the unified data management and integration is not well realized. Based on the analysis of the distributed and heterogeneous data characteristics, a data integration system with data integrality was proposed. The system introduced the mapping mechanism of three data mode （ inner mode, local mode and global mode） , established the architecture of hierarchical data model. Because of the architecture, the system could shield of heterogeneous data in the distributed and heterogeneous data environment. The system also proposed a data integrity check algorithm on the global mode. This algorithm would ensure the data integrity in the distributed and heterogeneous data environment. So the system could not only share the data resources, but also integrate the distribution of data resources. Finally, an application example in the earthquake data integration platform was described and analyzed, which showes this mechanism has the data integrity capability.
