Design And Implementation Of The Resource Integration Application Platform Based On The Service Digital Campus

Firstly,this thesis discussed the researched status quo of the digital campus and the service oriented architecture. Combined the digital campus construction item of Changsha Social Work College,it analysed the application status quo and existent question of the current campus internet with the ptimary clue of the service digital campus. It contrived systematically and demonstrated sufficiently the service digital campus from the various tache of system framework,hardware equipment,network layer framework,software architecture,security system and so on,bringed forward the construction scheme of the"1+N"application platform resource integration based on the service digital campus.The researchful emphasis of this thesis inclued information portal based on porlet and identity authentication based on Web Services,data exchange center basd on SOA and user concentration management based on LADP.According to the need of the campus information portal work mode,adopted porlet technology,realized the uniform information portal,effectively integrated each campus heterogeneous system,resolved system integration,information integration and individual information services.Adopted"browser-Web server-catalogue server"three tiers B/S structure, overpassed the secure standard of SAML,WS-Security and so on,realized uniform identity authentication,guaranteed faith between services and the credibility of message transmission. Clients entered portal site by these authentication technologies of gateway authentication,802.1x authentication and distributed authentication and so on. Portal used these three authentication ways:plain text,encrypted text or MD5-challenge,responded the user's enterance request according to the user's data stored by LDAP server.Utilized Realized the functions of the nuclear components by using these SOA nuclear technologies of JMS,Web Services,ESB and so on, for example the massage service on the data exchange platform,data transmission service and so on, established the data mapping relation between the oriented system and the target system via the mapping principle of the nonfigurative cyclostyle,realized data exchange and information share according to the mapping cyclostyle.Described the department and personnel information by using LDAP infonmation model,estalished UUMS,realized the classification and delamination management of user popedom in the campus internet,resolved these problems of user data synchronization,huge capacity inquisition,distributed and copied information.By integrating the operation flow between the applied procedure and information system,utilized sufficiently existing handware resourse,combined each service in and outside the campus,integrated and diffused gradually in the digital campus operation,changed the primary single service to mulriple services. Adopted the strategy of system security and uniform information portal,realized three functions of uniform identity authentication and management,uniform data exchange,uniform user management,established the service digital campus in the center of the packaged campus card and the system application platform with requirment.
