构建数据精确，功能完备、运行高效的数字化校园，必须针对学校业务现状，对校园信息管理系统进行整体规划，实现高内聚低偶合。采用分层结构设计方法可以降低数字化校园的设计难度；按经典的三层软件架构模型开发学校应用软件，可以降低层间的耦合度；通过绘制功能模块关系结构图，可以使数字化校园层次更清晰；通过绘制数据流图，可以梳理学校的业务逻辑，降低软件的开发和维护难度。

To builda digital campus with specific data,complete functions and efficient operation,should make an overall plan for the campus information management and achieve the high cohesion and low coupling in view of present situation of the college.To adopt the hierarchical structure design method can reduce difficulty in the digital campus design;to develop the college application software based on the typical three-layer software framework model can reduce the coupling between the layers; through drawing structural relation of the function module, hierarchy of the digital college will become more distinct; by drawing the data flow diagram(DFD),the college business logic can be combed and difficulty in the software development and maintenance can be lowered as well.
