网络的广泛应用给生活带来了十分的便利。所以把在线考试管理与现在网络相结合利用java技术建设在线考试系统实现在线考试的信息化管理。则对于进一步提高在线考试管理发展丰富在线考试管理经验能起到不少的促进作用。
在线考试系统能够通过互联网得到广泛的、全面的宣传让尽可能多的教师和学生了解和熟知在线考试系统的便捷高效不仅为高校考试提供了服务而且也推广了自己。对于在线考试而言若拥有自己的系统通过系统得到更好的管理同时提升了形象。
本系统设计的现状和趋势从需求、结构、数据库等方面的设计到系统的实现分别为管理员、学生和教师的实现。论文的内容从系统的设计、描述、实现、分析、测试方面来表明开发的过程。本系统根据现实情况来选择一种可行的开发方案借助java编程语言和MySQL数据库等实现系统的全部功能接下来对系统进行测试测试系统是否有漏洞和测试用户权限来完善系统最终系统完成达到相关标准。 关键字在线考试系统javaMySQL数据库
基于SpringBoot的在线考试系统源码和论文305
演示视频 基于SpringBoot的在线考试系统源码和论文 Abstract The wide application of the network has brought great convenience to life. Therefore, the online examination management is combined with the current network, and the online examination system is constructed by using java technology to realize the information management of the online examination. It can play a role in further improving the development of online examination management and enriching online examination management experience.
The online examination system can be widely and comprehensively publicized through the Internet, so that as many teachers and students as possible can understand and be familiar with the convenience and efficiency of the online examination system, which not only provides services for college examinations, but also promotes itself. For online exams, if you have your own system, you can get better management through the system and improve your image.
The current situation and trend of the system design, from the design of requirements, structure, database, etc. to the realization of the system, are the realization of administrators, students and teachers. The content of the paper shows the development process from the aspects of system design, description, implementation, analysis and testing. The system selects a feasible development plan according to the actual situation, realizes all the functions of the system with the help of java programming language and MySQL database, etc., and then tests the system to test whether there are loopholes in the system and test user permissions to improve the system, and finally the system Complete to meet relevant standards.
