In accordance with the digital campus construction experience and fact, this paper analyzed the principle and characteristic of SOA (service-oriented architecture) technology and proposed a kind of digital campus architecture based on SOA framework. The structure uses open standard protocols and the well interfaces and specifications defined among services. According to the actual needs, it can carry on distributed deployment, combination and application for loosely coupled coarse-grained applications through the network. Therefore, this structure can effectively solve "Information Island" and other problems in the campus platform. The SOA architecture has applied to our school digital campus construction many years. After application practice, the actual effect is remarkable. So the SOA architecture has certain reference significance and promotional value popularization value for the future digital campus construction management.
