Research On The Service-oriented Model Of Digital Campus For Universities

As rapid development of information technology, the construction of universities'educational informatization becomes important subject in the modern education. Owing to the limited of developing technologies and the unbalance of informatization development, each subsystem of departments is highly independent, lacking of relevance and thus information cannot be shared effectively, which prevents further developing of universities informatization seriously.This thesis puts forward a service-oriented model of digital campus for universities by studying problems and solving methods existing in digital campus construction. From macroscopic angle, the model designs service-oriented"T-F-F-T"hierarchical structure of digital campus construction based on independence of Web service platform and independence of programming languages, which could realize standard and loosely-coupled application architecture among systems. The model introduces service-oriented technology into digital campus construction, achieving goals that it can integrate subsystem reasonably, carry out deployment of educational resources flexibly, share and make full use of resources, be beneficial to system upgrade, renewal and extension.This thesis bases on service-oriented architecture and Web technology, mainly studies model of service-oriented digital campus construction, researches on the designing, planning and implementation of digital campus from both theory and development levels, establishes description of standard uniform informatization and realizes the uniform of application in campus service. It also designs comprehensive information service platform for digital campus(basic platform),containing campus united information portal platform, united identity authentication and authorization platform and data center(including data exchange and sharing platform).Meanwhile, it realizes application integration of systems (application support system of campus services not yet constructive) based on basic platform, raises a service-oriented integration scheme of digital campus based on the combination of data center and Web service after analyzing existing campus information system and the connection between data and service. Finally, relevant service has been supported as the integrated interface of systems.
