Research And Application Of Digital Campus Platform Based On CAS Model

During the rapid development of digitization and informatization,the proportion of informatization construction in campus management also increased gradually.New requirements had been raised by students,teachers and leaders at all levels about scientific research,administrative management and some other campus services,which prompted us to reconstruct and transform the original information platform.Under this background together with the actual business situation of Shandong University,Weihai,my paper mainly focus on the design and development of digital campus platform and several business subsystem.At present,our campus has set up perfect network infrastructure,and established a series of internal management system initially,but our existing business system is relatively scattered,lack of unified and specific entrance to integrate,a lot of repetitive manual operations still exit.High intensity and error-prone work could not only cause the redundancy of data,but also influence the timeliness of student work.My paper intend to establish the campus information portal on the basis of the Shared data center,build a unified authentication platform to validate login permissions,get through the flow of data and task between business,complete the inter-departmental coordination,reduce the informatization cost of campus and provide efficient campus life and business management services for the teachers and students so as to promote the overall management level and comprehensive strength of the campus,accomplish the comprehensive management of digital campus gradually.The main work done in this paper is as follows:1.To achieve a unified identity authentication platform.To conduct a unified management for the user identity and system permissions,standardize the application system,authentication method.2.To realize the campus informatization portal.To integrate the scattered data of campus life and business management information resources,provide classified application display under different permissions for teachers and students.3.To access to other in-school application subsystems.When the platform building is completed,we will take the education management system,orientation system,graduate-outgoing system,self-service payment system and a series of subsystems access to the platform,in order to achieve the effective flow of business data.This system is mainly developed by using Java programming language,based on Spring,Struts,Hibernate(SSH)integrated framework.The single sign-on service uses Yale University's open source central certification service framework-CAS,and is improved on this basis.Oracle database and Tomcat server,respectively,as a data container and application containers.The MVC design pattern promoted by the SSH framework realizes the separation of the data layer,the business layer and the display layer of the system,makes the system run more stable and makes the development and maintenance more efficient.
