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。
