Digital Campus Shared Data Center Construction And Implementation

Educational patterns and environment have changed greatly as the result of the development of information technology. Currently, the information management system has been introduced into the colleges and universities to improve the work efficiency. However, due to lack of unitive programming between the various sections in colleges and universities, these data turn out to be irregular and non-authoritative. Moreover, the resources waste and failure to share data have been caused for the various degrees of informationization of sections and the irrelevance of developing environment, database and operating platform.Based on the background of digitalized campus, the relevant knowledge has been introduced and the construction of datacenter has been particularly analyzed in the process of campus digitalization. During the research, in accordance with the data irregularity of business system, the data dictionary of each business system has been under study firstly to meet the needs of data integration and to learn the current informationization. Taking advantage of the characteristics of webservice, the technology of data stream transform and transmission, which is built on XML interface, has been applied in the realization of data exchange between the data center and the business system. Analysis on two measurements of writing in synchronous-meters of the data currently existed has been carried in the data uplink modules of the data center, and the xmldiff writing mode has been therefore suggested to be adopted. In the data downlink module, SDCwebservice is suggested to be the media of the business system and the sharing data center. The data security has been insured by the inquiry result transmitted with XML. Ultimately, the process of the data exchange between the library and the data center is taken for instance to explain the data transmission between the data center and the business system on the digitalized campus.
