Abstract :
Based on the study of data integration in the unified information platform of heterogeneous e-government system and the investigation of the design of e-government, the technology of topic maps and the relational database, a new data integrated model was issued. According to the analyze of relational database, this model realizes the data integration of the heterogeneous e-government system which generate a cross system subject index layer between the application layer and the data layer in several heterogeneous e-government system and use the technology of OAI-based metadata harvesting as well as the auto-generation and auto-combination of topic map.
