排球比赛计分，现场工作人员
1． 估计时间：一周左右。
2． 开发
需求分析：
作为一个排球比赛的现场工作人员，我需要统计每一名
队员的得分及技术统计，以便颁发每场比赛的最有价值球员奖，
以及确定赛会的最佳阵容。
设计文档：
在界面可以通过datagridview或txtbox控件队球员信息进行操作，可以同步到数据库中。通过botton按钮查询分数和统计页面。从数据库中获取运动员分数并进行排序，得出最高分。并显示到页面上。
设计复审：
自己。
代码规范：
用到access和c#对设计进行具体操作；
具体设计：
界面：
后台代码；

代码复审：
无
测试：
当前功能可以实现。
工作量统计：
数据库40%代码50%界面10%；
事后总结：
对于数据库的操作较为生疏，后台代码运行时也有困难。比较上次，这次至少知道了整个流程。对于三层架构不能熟练使用。具体功能的实现要多于其他人交流。以上就是这次的总结。
