结对开发石家庄地铁
要求:
1.开发一套石家庄地铁线路查询系统。
2.功能设计
(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。
例如输入出发地:石家庄铁道大学 目的地 博物院
返回经历的站名的个数,和路径,如果有换乘,请列出换乘的线路
队友:马硕
数据库:
这只是一部分,线路较长,就不全部显示了。
剩下的就是开发的事情了,
观察地图
我们得出的结论是,最多两次换乘之后,便能完成任务,我们按照这个思路来开发,
这是我们的构架
在这其中Linksql是一个工具包,搬过来修改一下数据库就可以用了,basic是基础,存的是一个站点的信息,既建立数据库时的信息,
