简单版问卷调查系统(Asp.Net+SqlServer2008)

1.系统主要涉及以下几个表 

问卷项目表(Q_Naire) 问卷题目表(Q_Problem) 题目类型表(Q_ProblmeType)

题目选项表(Q_Options) 调查结果表(Q_Answer) 参与用户表(Q_User)

2.涉及的存储过程

pNextID 获取实体表主键ID

sp_NaireAnswer 将问卷调查的结果写入结果表(通过WebService方法调用)

sp_NaireImport 通过导入的问卷数据生成问卷项目(根据Q_Naire_Import表中的问卷数据分别写入Q_Naire、Q_Problem、Q_Options中生成问卷)

sp_NaireResult 问卷调查结果数据集

3.系统实现方式

后台：主要是通过后台维护的问卷数据，根据问卷项目编号获取问卷题目以及题目类型

然后根据题目类型在后台生成相应的控件，后台控件生成通过Asp.Net实现

结束语:

时间关系，只是作了简单的问卷展示页面，其他维护性页面都没有做。直接在后台数据库处理的。有兴趣的朋友可以完善下。写的很粗糙，欢迎大神拍砖。
