数据流图实验 实验目的 通过绘制数据流图掌握数据流图的基本原理，并能对简单问题进行数据流图的分析，独立地完成数据流图的分析与设计。此外，学会使用Case工具完成数据流图和系统流程图的分析与实现。 实验内容 实验内容如下： 用visio绘制出如下定货系统的SFD（系统流程图）的模型。 图1 某定货系统SFD 用visio绘制教材中分别绘制出定货系统的DFD的顶层模型、第一层模型和第二层模型。（具体参考课本上P69~P70的图3.4，图3.5和图3.6） 用visio 绘制如下图所示的取款手续的数据流图。 图2 取款手续 请结合目前的银行柜台取款手续，对图2的取款数据流图进行改进，绘制当前银行柜台取款过程的顶层和第一层数据流图。 实验结果 图1 某定货系统SFD 图2 顶层模型基本元素 图3 完整的L1层模型 图4 完整的L2层模型 图5 顶层模型基本元素 图6 完整的L1层模型 图7 完整的L2层模型 force (youth teams) and County party leaders, aimed at weakening the anti-Japanese forces. Zhuang Shaozhen was removed from Office and to the underground revolution activities carried out in the country, political parties were dissolved. Zhejiang comrades and thus losing a foothold in Wujiang basis points. To make them stay, jindapeng served as captain of the young workers through activities, make the political player-wise into the youth team. Save a group of the backbone of the resistance, and gave the Communists ... Commander Zhu Xi, led by Deputy Commander Wang Hesong, stationed along the junction of Jiangsu xincheng, Wuzhen. Zhu Xi troops KMT-CCP cooperation and anti-Japanese policy of solidarity, he moved to Jiangsu and Zhejiang provinces. Zhu Department times and day Army hand-to-hand combat made victory, grow has momentum, standing strict Tomb, and new Cheng of appeasement army giant Haru Brigade anyway, received adapted; living Taihu Lake of bin of two a even Hunan army with of allegiance; Jiangsu and Zhejiang junction area of Wang Chunlin Department about 500 people also has done a Yu Zhu Xi men; River, and Zhejiang, and Shanghai area many tour miscellaneous forces also attracted attached return, plus many local youth have joined forces, Zhu Xi strength big increased, from original more than 200 more people quickly development to more than 4,000 more than people, opened has a to Wuzhen for Center, including strict Tomb, and Shuanglin, practicing guerrilla base of the urban, new Cheng became strongest gu
