一、项目简介
汽车维修项目管理系统使用Java语言进行编码,使用Mysql创建数据表保存本系统产生的数据。系统可以提供信息显示和相应服务,其管理汽车维修项目管理系统信息,查看汽车维修项目管理系统信息,管理汽车维修项目管理系统。
二、系统设计
2.1软件功能模块设计
在前面分析的管理员功能的基础上,进行接下来的设计工作,最终展示设计的结构图(见下图)。
2.2数据库设计
(1)下图是出入库详情实体和其具备的属性。
(2)下图是用户实体和其具备的属性。
(5)下图是员工实体和其具备的属性。
(6)下图是维修项目评论实体和其具备的属性。
三、系统项目部分截图
3.1用户信息管理
如图5.1显示的就是用户信息管理页面,此页面提供给管理员的功能有:用户信息的查询管理,可以删除用户信息、修改用户信息、新增用户信息,
还进行了对用户名称的模糊查询的条件
3.2维修项目管理
如图5.2显示的就是维修项目管理页面,此页面提供给管理员的功能有:查看已发布的维修项目数据,修改维修项目,维修项目作废,即可删除,还进行了对维修项目名称的模糊查询 维修项目信息的类型查询等等一些条件。
3.3维修项目类型管理
如图5.3显示的就是维修项目类型管理页面,此页面提供给管理员的功能有:根据维修项目类型进行条件查询,还可以对维修项目类型进行新增、修改、查询操作等等。
四、部分核心代码
