大家好，我是全微毕设团队的创始人，本团队擅长JAVA(SSM,SSH,SPRINGBOOT)、PYTHON、PHP、C#、安卓等多项技术。
今天将为大家分析一个车辆故障管理系统（本文针对汽车故障诊断专家系统 中知识库的特点,设计了一种基于Windows平台的知识库管理系统(KnowledgebaseManagementSystem以下简称KBMS), 该系统充分利用了数据库技术,实现了对知识库中知识的存储、增加、删除、修改和查询,以及对知识进行一致性和完整性校验,为汽车故障诊断专家系统的开发和 运用奠定了重要基础。），该项目使用框架为SSM(MYECLIPSE)，选用开发工具为MYECLIPSE。车辆故障管理系统为一个 后台项目。
为了完成该系统，我们首先需要对该系统进行需求分析。一个车辆故障管理系统应包含用户角色有管理员、车主、员工。为了能让用户顺利登陆系统完成相关操作，需要为每种登陆角色设置账户和密码字段。
为了完成系统的功能需要为车主设置车辆表，记录车辆信息。在车辆表中定义了两者的关联关系，其中车辆的车主与车主的mingzi字段对应、车辆的车主id与车主的id字段对应
。
总结得出该系统所有数据为：管理员(admin)、车辆(cheliang)、车主(chezhu)、员工(yuangong)
管理员表
字段名 | 类型 | 属性 | 描述 id | INT(11) | PRIMARY KEY | 管理员id username | VARCHAR(255) | | 账号 password | VARCHAR(255) | | 密码
车辆表
字段名 | 类型 | 属性 | 描述 id | INT(11) | PRIMARY KEY | 车辆id chepai | VARCHAR(255) | | 车牌 chezhu | VARCHAR(255) | | 车主 chezhuid | VARCHAR(255) | | 车主id zhuangtai | VARCHAR(255) | | 状态
车主表
字段名 | 类型 | 属性 | 描述 id | INT(11) | PRIMARY KEY | 车主id mingzi | VARCHAR(255) | | 名字 lianxi | VARCHAR(255) | | 联系方式
员工表
字段名 | 类型 | 属性 | 描述 id | INT(11) | PRIMARY KEY | 员工id mingzi | VARCHAR(255) | | 名字 username | VARCHAR(255) | | 账号 password | VARCHAR(255) | | 密码
