12306最重要的功能就是实现购票，退票，改签三大功能，这些属于乘客要实现的功能。购票，就像我们平时乘车买票，需要规范输入自己的姓名，手机号，还有身份证号，然后调取数据判读信誉度是否可以买票。退票查找到个人的狗牌记录然后删除。改签其实就是先退票后购票，然后稍微改动一下。
管理员需要实现对站点的增加，两个站之间增加一个站点，输入站点的名称，经过的车次号，到站时间，出站时间，在这个站点放多少票。删除站点就把次站点的所有信息删除。修改站点，我是先把站点的所有信息删除然后再添加新的站点信息。增加乘客信息，需要添加乘客的姓名，手机号，身份证号，还有信誉度，信誉度不足的乘客是不允许乘车的，管理乘客功能主要就是对乘客的信誉度进行管理，如果该乘客做了违法乱纪的事情，就把他的信誉度变为0，不可乘车买票。 接下来就是查询功能，查询的话要根据车次号来查询把中间经过的站点还有到站时间，出站时间全部输出。还要根据始发站和终点站来查询，然后把有座的列车都输出来，并且输出始发时间和到站时间。还需要查询每个乘客的乘车记录，输入姓名就能查询到乘车记录，包括始发站，终点站，车次号，发车时间，到站时间。查询功能是乘客和管理员都有使用的，所以单独写一个类，然后用来继承。
