We present the topological structure of MCP, system infra- structure, application architecture and the data management (such as data integration, data format translation, data security control and so on) of our mobile campus portal in this paper. After online running in the past two years, our MCP has received good feedbacks from mobile users. In the future, we will focus on the research of data-mining technologies in our big data environment.展开更多
