摘 要
互联网发展至今,无论是其理论还是技术都已经成熟,而且它广泛参与在社会中的方方面面。它让信息都可以通过网络传播,搭配信息管理工具可以很好地为人们提供服务。针对实验室信息管理混乱,出错率高,信息安全性差,劳动强度大,费时费力等问题,采用智慧城市实验室主页系统可以有效管理,使信息管理能够更加科学和规范。
智慧城市实验室主页系统在Eclipse环境中,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,本系统管理员管理电子期刊,国际会议,学术团队以及实验动态,管理奖项和活动以及设备信息。教师管理科研报告,管理科研成果,下载国际会议资源,参与学术交流。学生下载科研成果,会议资源,电子期刊文件,查看学术交流里面的帖子并发布评论,查看学术团队,实验动态等信息。
总之,智慧城市实验室主页系统集中管理信息,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。
