一、功能要求
1.数据库设计：将石家庄地铁线路图的各个线路，各个站点，换乘信息等用数据库的形式保存起来，应该保存的信息有 {线路号，线路的各个站名，车站的换乘信息}。
2.站点查询：用户可以输入任一一条线路或输入出发地和目的地信息，可以查询到相关内容。
2.站点查询：用户可以输入任一一条线路或输入出发地和目的地信息，可以查询到相关内容。
二、合作对象及开发日志
合作对象：符满迪、何祺祺

| 2019.4.2 | 8：00 | 9：35 | 无 | 1.35h | 实现两个站点的查询功能 |
| 2019.4.3 | 16：30 | 20：40 | 18：00 | 3h | 悬浮窗设计，以及查询算法的完善 |
| 2019.4.4 | 8：00 | 9：35 | 无 | 1.35h | 完善界面，测试程序 |
三、设计思想及程序代码
1.设计思想：本次结对开发任务分工合作，符主要负责web界面的设计以及地图的实现，何主要负责数据库的设计，最终两人一起完成查询算法的实现。
数据库设计主要设立了三个表，分别是站点表（stop）、路线表（line）、站路关系表（line_stop），主要经过站路关系表实现查询算法。
而web地图界面的设计，我们调用了百度地图的api接口，实现了线路之间的连接，美中不足的是，地图上没有完整的石家庄地铁线路，需要自己将另外4条直线连接起来，整个界面就显得十分抽象。
2.程序代码：
地图展示web界面（利用html实现）：
