论文目录
【如需全文请按文末获取联系】
一、项目简介
基于web的校园报修系统使用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,总之,基于web的校园报修系统集中管理信息,有着保密性强,效率高,存储空间大,成本低等诸多优点。它可以降低信息管理成本,实现信息管理计算机化。
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
(2)下图是学生实体和其具备的属性。
(3)下图是维修人员实体和其具备的属性。
(5)下图是故障上报实体和其具备的属性。
(6)下图是故障上报评价实体和其具备的属性。
三、系统项目部分截图
3.1学生信息管理
如图5.1显示的就是学生信息管理页面,此页面提供给管理员的功能有:学生信息的查询管理,可以删除学生信息、修改学生信息、新增学生信息,
还进行了对用户名称的模糊查询的条件
3.2维修人员管理
如图5.2显示的就是维修人员管理页面,此页面提供给管理员的功能有:查看已发布的维修人员数据,修改维修人员,维修人员作废,即可删除,还进行了对维修人员名称的模糊查询 维修人员信息的类型查询等等一些条件。
3.3故障上报管理
如图5.3显示的就是故障上报管理页面,此页面提供给管理员的功能有:根据故障上报进行条件查询,还可以对故障上报进行新增、修改、查询操作等等。
