论文目录

【如需全文请按文末获取联系】

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。
