Research on Data Synchronization Consistency Comparison System Based on Computer Heterogeneous Database

Aiming at the problem of heterogeneous data consistency verification, this paper proposes a verification method based on XML tools. The system determines the elements to be transformed in CIM/RDF through SAX parsing, and designs a deep search algorithm to get the mapping rule base of the classes and attributes to be transformed. Then we propose a hash retrieval algorithm based on CCA (canonical correlation Analysis) semantic consistency (CCA-SCH). In order to maintain the semantic consistency within the mode, the algorithm generates semantic models of text and image data respectively. By comparing the output results of multiple heterogeneous function executors, the abnormal detection of function executors was carried out. The system implements active defense of the routing system. The results in this paper provide a model mapping basis for heterogeneous model interaction and help to realize the identification and interaction of heterogeneous model on the information exchange bus.
