一、项目简介
系统主要分为管理员角色和用户角色，具体的功能设计包括注册登录管理、用户信息管理、车辆信息管理、保养登记管理等模块。
二、系统设计
2.1软件功能模块设计
本系统的总体功能设计图如图4-1所示。
2.2数据库设计
图4-2管理员信息E-R图
图4-3用户信息E-R图
图4-4 用户信息E-R图
图4-10系统总体E-R图
三、系统项目部分截图
3.1个人中心
通过设计的个人中心管理功能模块，管理用户可以对相关的个人信息进行管理，比如管理用户可以更新个人账号的密码信息，修改个人账号的用户名信息等，修改密码界面设计如图5-1所示，个人信息界面设计如图5-2所示。
3.2员工管理
通过设计的员工管理功能模块，管理用户可以管理相关的员工信息资料，比如进行查看员工姓名，修改员工联系方式，删除已经注销的员工信息记录等操作，员工管理界面设计如图5-3所示。
3.3用户管理
通过设计的员工管理功能模块，管理用户可以管理相关的用户信息资料，比如进行查看用户姓名，修改用户联系方式，删除已经注销的用户信息记录等操作，用户管理界面设计如图5-4所示。
