一.前言介绍及开发技术
垃圾分类管理系统首先可以大幅提高医药垃圾分类管理信息系统检索，只需输入相关信息就能在数秒内反馈想要的结果；其次可存储大量的医药垃圾分类信息，同时医药垃圾分类管理系统安全性有更高的保障；相比纸质文档来管理医药垃圾分类信息，医药垃圾分类管理系统更节省空间人力资源。这些优点大大提高管理效率并节省运营成本。本系统为了数据库结构的灵活性所以打算采用MySQL来设计数据库，而java技术， B/S架构则保证了较高的平台适应性。
二.功能设计
管理员登入使用本系统涉到的功能主要有个人中心、公告信息管理、用户管理、垃圾分类管理、医院垃圾信息管理、留言反馈管理、管理员管理等功能。用户登入使用本系统涉到的功能主要有个人中心、医院垃圾信息管理、留言反馈管理等功能。
三.功能截图
系统登录，管理员和用在登录页面选择需要登录的角色，在正确输入账号和密码后，进入操作系统进行操作。
管理员进入主页面，主要功能包括对个人中心、公告信息管理、用户管理、垃圾分类管理、医院垃圾信息管理、留言反馈管理、管理员管理等进行操作。
管理员点击公告信息管理。进入公告信息页面输入公告标题和选择公告类型可以查询，新增或删除公告信息列表，并根据需要对公告详细信息进行查看详情，修改或删除操作。
管理员点击用户管理。进入用户页面输入用户名和姓名可以查询，新增或删除用户列表，并根据需要对用户详细信息进行查看详情，修改或删除操作。
管理员点击垃圾分类管理。进入垃圾分类页面输入垃圾分类可以查询，新增或删除垃圾分类列表，并根据需要对垃圾分类详细信息进行查看详情，修改或删除操作。
管理员点击医院垃圾信息管理。进入医院垃圾信息页面输入垃圾名称和选择分类可以查询，删除或分类统计医院垃圾信息列表，并根据需要对医院垃圾详细信息进行查看详情，修改或删除操作。
管理员点击留言反馈管理。进入留言反馈页面输入反馈日期可以查询或删除留言反馈列表，并根据需要对留言反馈详细信息进行查看详情，修改或删除操作。
管理员点击管理员管理。进入管理员页面输入用户名可以查询，新增或删除管理员列表，并根据需要对管理员详细信息进行查看详情，修改或删除操作。
用户进入主页面，主要功能包括对个人中心、医院垃圾信息管理、留言反馈管理等进行操作。
用户点击医院垃圾信息管理。进入医院垃圾信息页面输入垃圾名称和选择分类可以查询或新增医院垃圾信息列表，并根据需要对医院垃圾详细信息进行查看详情操作。
用户点击留言反馈管理。进入留言反馈页面输入反馈日期可以查询或新增留言反馈列表，并根据需要对留言反馈详细信息进行查看详情操作。
