选择了网络印刷服务平台数据流模型的建模方法,分析并建立了平台系统的顶层数据流模型,在此基础上建立了平台的1 层数据流图,依据对1 层数据流图各节点的细化研究,进一步实现了2 层数据流图的分析与建立,从而实现了网络印刷服务平台数据流模型的建立,为网络印刷服务平台中数据的收集、整合以及传输研究提供依据。

Modeling methods of data flow model of web-to-print services platform were selected and the top-level data flow model was established. First layer data flow diagrams were established. 2nd layer data flow diagrams were established based on research of each node of the first layer data flow diagrams. The establishment of the data flow model for web-to-print services platform was finally realized. The purpose was to provide basis for the data collection, integration and transmission of web-to-print services platform.
