An Integration Method of Digital Campus Resources based on Heterogeneous Data Integration

In this paper we study how to effectively integrate digital campus resources through a heterogeneous data integration algorithm. A framework of heterogeneous data integration based on working process design is proposed. In the proposed framework, in order to integrate different data resources, we call on the corresponding local Web service query exploiting XML documents. Then XML based Heterogeneous data integration algorithm is designed by converting the different data resources integration problem into a multiple XML tree merging problem. Next, inspired by the proposed heterogeneous data integration algorithm, digital campus resource integration scheme is developed in three main layers of data layer, middle layer and application layer. We then consider seven sub-systems in digital campus construction. To do performance evaluation, experiments are carried out to testify the effectiveness of the proposed design. The results demonstrate that exploiting the proposed algorithm various information systems can be effectively integrated into the digital campus resource sharing platform.
