  • 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.
