资源简介

1.1 课题研究现状分析    在各大高校里,实验设备各式各样。在实验设备的管理中,如果通过使用计算机可以减少大量的手工操作,提高工作效率。实验设备管理系统过去采用人工处理方式,由于工作量非常之大,为了提高工作效率,方便管理,因此需要开发一个实验设备管理系统。    本次课题为:实验设备管理系统,它的主要功能是先通过用户身份验证,然后即可登录实验设备管理系统,然后通过增、删、查、改操作对实验设备信息进行管理和维护。 1.1.1 本领域内已开展的研究工作    1.理论研究基础    (1)后台以SQL数据库支持。    (2)前台以 NeatBeans为开发环境,实现学生基本信息管理的增、删、查、改操作。    2.技术层面的支持    (1)系统的设计与实现应采用MVC分层模式。    (2)系统界面采用MDI方式,即用户登录后进入主窗体,主窗体通过菜单进入子窗体。
