数据库课程设计 语言要求：java和MySQL 要求：设计一个系统像Uber一样能实现叫车服务。必须使用数据库进行数据存储，必须是做成一个网页上传到服务器（数据库也在服务器端），然后老师可以在自己的电脑上输入网址来访问这个网页。 具体要求：有一副地图显示人所在的位置（这个地图可以随意自己找一个城市的固定地图，例如洛杉矶downtown），然后输入10，代表显示周围十公里内的车，然后在地图上显示出一个个小点，点击这个小点，就能选中这辆车。然后通知这辆车的驾驶员与其联系。 所以说我个人的理解是数据库至少要有这几张表：第一个是保存用户信息的，第二个是保存司机信息的，第三个是保存当前在线司机的信息的（地点坐标），代表了现在有几辆车待命，他们的位置又在哪。 其他的表我就不是很清楚了。 文档要求：数据库的关系模型，数据库的ER图，SQL 语句 最主要目标是做好这个网页，老师不看代码，只要发给他URL即可。 因为老师根本没有给出具体要求的文档，就是说要设计一个系统像Uber一样能实现叫车服务。必须使用数据库进行数据存储，必须是做成一个网页上传到服务器（数据库也在服务器端），然后老师可以在自己的电脑上输入网址来访问这个网页。 请问下价格评估 还有时间是一周内 不是的，不要真的和出租车合作的 是自己在数据库中输入一些出租车的位置 然后进行查找 然后网页上应该是有给司机注册的，还有给用户进行注册的 然后数据的话不是实时数据，只是预先输入进去的数据，例如自己输入100辆出租车的位置信息到数据库中 对，用java，数据库类型MySQL 因为这两个我看得懂 如果真要解释的话我也能扯一下
