An Integration Model of Multi-Source Heterogeneous Audit Data

Abstract

This paper shows the problem of multi-source heterogeneous data integration in the audit data storage and access problems. Based on the analyses of existing data integration model, combining with the service-oriented architecture theory, this paper proposes a data center pattern, which is suitable for multi-source heterogeneous data integration model to audit. Furthermore this paper puts forward an incremental based technology to show the problem of synchronization of business audit data integration model, and expounds the data management mode based on Middleware technology. To the above problems, based on the analysis of the existing data integration models, combining with the service- oriented architecture theory, this paper puts forward a suitable model for multi-source heterogeneous data integration of audit data center; further based on analyses about the hierarchical structure of the model, provides the basis for data integration application stage data display, query, analysis.
