快递分拣系统
一、 项目设计分析：该快递自动分拣系统主要用于快递管理员对快递包裹信息进行录入，删除，修改，查询，对快递内容的检测等操作，和客户对于快递包裹信息，快递物流信息的查询以及对当地快递拣货点的查询，方便人们寄领快递，保证人们身份信息及个人隐私的安全性。
二、 程序功能简介：该系统共有以下十一个功能
1登录注册功能：用户可以用用户账号登录系统，管理员可以用管理员账号登录系统。
2查询用户信息：用户可查询用户的所有信息，管理员可查询所有用户信息。
3修改用户信息：用户可以对用户账号进行用户名修改，密码修改和密保修改，管理员可以对管理员账号进行密码修改和密保修改。
4增加快递订单：用户可填写快递单号，选择快递公司及邮费，系统自动生成订单创建时间，订单删除时间，订单修改时间，订单保存时间。
5删除订单：用户和管理员可以删除订单信息，登录后按照主菜单提示，选择订单信息，之后进入菜单选择删除订单信息，再之后系统提示按照所需条件删除订单信息系统自动生成订单创建时间，订单删除时间，订单修改时间，订单保存时间
6更改订单：用户和管理员可更改订单信息，登录后按照主菜单提示，选择订单信息，之后进入菜单选择更改快递订单信息，再之后根据系统提示按照所要更改的条件更改相应的订单信息，系统自动生成订单创建时间，订单删除时间，订单修改时间，订单保存时间。
7 查询订单信息：用户和管理员可查询增加的快递订单信息，系统自动生成订单创建时间，订单删除时间，订单修改时间，订单保存时间。管理员能查看所有订单信息。
8 增加详细快递信息：用户根据系统提示可填写快递详细信息。
9查询详细快递信息：用户和管理员都可以查看分快递包裹详细信息，登录后按照主菜单提示，选择包裹信息，之后进入菜单选择查询包裹信息，再之后根据系统提示按照所有查询的条件查询特定信息，管理员能查看所有详细快递信息，管理员可查看所有详细快递信息。
10删除详细快递信息：用户和管理员时可对已存在快递详细信息进行取消功能，登录后按照主菜单提示，查询快递包裹信息后若存在则可按照系统提示进行取消订单的操作。
11更改订单；用户和管理员可对已存在详细快递信息进行更改功能，登录后按照主菜单提示，查询快递包裹信息后若存在则可按照系统提示进行个更改订单的操作。
