Research And Implementation Of Digital Campus Data Center

With the development of information technology, Digital Campus Construction ispopularized. However, due to the lack of unified planning in the construction, the data fromvarious business systems are obtained without uniform standard, and various operatingplatforms and databases are lack of effective interface, which results in the situation of"lonley island of information". Thus data center comes into being. Data center provides datastandard and ensures the exchange and sharing of data, which makes data become safer andfaster to use. Through participation in the project of “Data Center Construction of DigitalCampus” undertook by the Ideal IT Institute of Northeast Normal University, the authorproposes a program on the data center construction of Digital Campus. The program is builtbased on the standard of “Request fordraft of Standard on Education ManagementInformation (Series)” released by the general office of the Ministry of Education.This paper first describes the function, structure and deployment of data center. Second,combined with actual business needs of the school, the business process of data center inDigital Campus is designed based on UML. And in the study on key technologies of the datacenter system, four parts are included. In the first part, in accordance with the standard for acentral repository from provisions of the Ministry of Education, the building and use of acentral repository is illustrated; in the second part, the sharing model of database in datacenter is discussed, and in the system, with the use of straight-chain solution for web serviceand database, the connection type of the business system and data center is figured out; in thethird part, referring to the data security of data center, the system adopts timing control of atrigger to ensure the data security, with communication encryption and message encryption;and the fourth part talks about web services of data center to provide a design for the webservices construction in Digital Construction. Finally, according to the data center design,data center of Digital Campus in high school is set up, and after being verified, the proposedconstruction design is feasible.Currently, data center of Digital Campus for high school has been in a trial in a middleschool in Changchun City. The results of the trial shows that the proposed constructionprogram is reliable, and the software developed, which can be used, is of goodpopularization.
