An Intercity Heterogeneous e-Government Data Integration Model Based on Topic Map Technology and Database Analysis

摘要：

Data integration for the unified web-based information platform of heterogeneous e-Govemment system becomes the most important issue in eGovernment system conformation. This paper proposes a new model of data integration based on in-depth analysis of Topic Map technology and Relational Database Management System (RDBMS). This model uses OAI protocol for Metadata harvesting to automatically generate a topic index layer between the application layer and data layer of e-Government systems. To integrate the intercity heterogeneous e-Govemment systems, we derive topic maps in the topic index layer by identifying topic, association and occurrence of each topic map in the RDBMS, and then amalgamate topic maps by measuring their similarities.
