实验室管理系统课程设计

2018-06-18 03:59:10来源:未知 阅读 ()

新老客户大回馈,云服务器低至5折

主要目的:实现对实验室的硬件资源和软件资源的使用和管理。
数据信息:用户登录信息(分普通成员--管理员:信息主要有用户名、密码、性别、专业班级、学号、联系电话、QQ等)
硬件器材信息(编号、名称、数量、存放地点、所属类别、主要用途)
图书资源信息(图书编号、图书名称、图书数量、图书类别、主要用途)
主要功能:
1.登录界面:实现不同用户的登录、找回密码、注册新用户。
2。普通用户登录之后功能选择:查询资源记录、借还资源、修改个人信息。
3.管理登录可以增加新的耗材记录、修改用户信息。
