Digital Campus Data Center Platform

The modern university campus is a digital university.A university resource planning(URP) resolution was proposed to solve problem in education informatics such as lack of planning,no sharing of resources,difficulty in application integration.With the application of URP system,a universe database system must be designed to support the identity management and the sharing of data of multiple application systems.The LDAP(Lightweight Directory Access Protocol) directory service is a cross platform service,base on the LDAP unified user management system,provide the distribution access and management of identity data.With the directory service, system security is enhanced and the cost of management is reduced.Shared database is another core service in digital campus,which is the fundamental of imformation service of digital campus applications.Data are integrated from all the product databases into the shared database to form a shared data center to support the share of data among multiple systems.The design of shared database can ensure the responsiveness,interative and consistence of data in the system.Based on the detailed analysis of a number of colleges and universities on the present situation and in a view of URP,this papar choose a suitable method to design a unified database to build a shared database center and unified authtication platform:Build database of directory service with the LDAP protocol, providing the universe data access and storage.With the Sun Identity Server,a unified identity authentication system was implemented,and SSO feature was enabled in the system;Design and build the shared database system and data exchange platform,which integrate the date in product databases and the data in shared data center.Several utilities to maintain the database system was build with the shared database system.
