| Abstract: This paper presents a solution to the integration of the online examination system in the heterogeneous environment.Without affecting the original system,an integrated platform is constructed to implement the conversion of heterogeneous database to the XML format file,and data can be shared on the online examination system in the heterogeneous environment.The paper focuses on the design and implementation of the integrated heterogeneous online examination system,such as the requirements of the heterogeneous data source,the design of the system function module,and the design of the XML data integration.Including the design of the wrapper,the query processing module and the structure processing module,the paper implements the conversion integration from different database to XML format data,and the sharing of heterogeneous data in the online examination system. |
