为了资源的节约有效利用，使车辆发挥更大的作用，我在此做了一个租车系统。

功能分析：
1：登录功能
2：后台管理功能
3：车辆管理功能
4：用户管理功能
5：前台用户功能
6：查看可租车辆信息功能
7：查看已租记录功能

选择角色后会让你输入账户和密码（输入的账户密码不对会让你重新输入）

实现此程序数据库使必不可少的

下面看SQLServer数据库构成（三个表）

1 . 用户表（user）

2 . 车辆表(vehicle)

3 . 租赁记录表(rent_relation)

在程序正式开始之前我们先看一下**目录结构图**

由于结构图较长分为二部分展示

相信你们已经迫不及待想要看代码了，下面就让我们一起来分析欣赏代码.
