With the rapid development of information technology, information technology colleges and universities have entered a new stage of digital campus construction phase. From the application side, the foundation for building digital campus is data integration. This paper starts targeted research on the construction of digital campus in the data integration problems. It designs and implements a service-oriented data integration model. The proposed model can help to solve the heterogeneous data integration, distribution, autonomy issues. Paper focuses on the following aspects:First and for most, this paper utilizes service-oriented design to propose service-oriented data integration methods focusing on the inadvance of traditional data warehouse solutions in digital campus .Based on service-oriented approach, this paper designs a service-oriented data integration model. The model is based on Web Service technology and XML technology to achieve to solve the heterogeneous data integration and distribution issues. Layed structure and component technology are used to achieve a loose coupling between the various functional modules which increasing the flexibility of the system. In particular, the reflection is introduced into the design of the model, making the model to dynamically adapt to frequent changes in data sources, making the model more practical and robust.Second, Basing on the data in service-oriented integration model and focusing on the packaging and integration of the data, this paper designs a data structure model and the intermediate packaging structure model. The design of the two extensive use of technology is on the basement of reflection. With the overall model design, it can maximize the shielding of the autonomy of data integration problems caused by frequent changes in data sources which is frequently caused by system reconfiguration.Finally, Jiaxing University Digital Campus data integration system for example, it details the model implementation and verifies the reasonableness, feasibility and effectiveness of the related technology.
