使用旧方法对开放实验室预约管理系统的信息进行系统化管理已经不再让人们信赖了，把现在的网络信息技术运用在开放实验室预约管理系统的管理上面可以解决许多信息管理上面的难题，比如处理数据时间很长，数据存在错误不能及时纠正等问题。这次开发的开放实验室预约管理系统对字典管理、公告管理、课题报名管理、老师管理、实验室管理、实验室预约管理、学生管理、管理员管理等进行集中化处理。经过前面自己查阅的网络知识，加上自己在学校课堂上学习的知识，决定开发系统选择小程序模式这种高效率的模式完成系统功能开发。这种模式让操作员基于浏览器的方式进行网站访问，采用的主流的Java语言这种面向对象的语言进行开放实验室预约管理系统程序的开发，在数据库的选择上面，选择功能强大的Mysql数据库进行数据的存放操作。开放实验室预约管理系统的开发让用户查看实验室信息变得容易，让管理员高效管理实验室信息。
