1.2 Scope
(1)软件产品：“捐赠平台”微信小程序
(2)预期功能：
学生通过学号注册和登录；
学生可以将自己不需要的书籍，衣物等其他物品捐出，在应用上上传信息和图片；
由学生组织工作人员审核所发信息；
通过之后会留言给学生，之后方便进行线下交易；
可记录学生通过这个平台所获取的总志愿时长，有明确的时间，授权组织；
如果学生有违约行为，可经工作人员处理，暂时封号或者扣除志愿时长；
(3)软件产品的应用：
该软件旨在搭建一个志愿组织和志愿者的交流平台，方便志愿组织进行相关信息的发布以及志愿者的参与，为双方提供便利。同时对该平台通过后台管理进行维护以及更新。做到能够及时通过收到的反馈信息进行调整。
1.3读者对象和阅读建议
对象：项目管理者，设计人员和测试人员。
阅读建议：着重对产品功能的分析上；可以通过查看附录的建模来大致快速地了解该项目。

2.总体描述
2.1产品前景
应用于学校内，但是后续可以扩展范围到多个学校之间或者北京市、镇、区。
如果小程序已经不满足广大学生的需求，可以考虑扩充容量。
2.2产品功能
信息发布；
学生通过学号注册和登录；
学生组织认证；
学生可以将自己不需要的书籍，衣物等其他物品捐出，在平台上上传信息和图片；
学生组织工作人员审核所发信息；
