摘 要
在如今社会上，关于信息上面的处理，没有任何一个企业或者个人会忽视，
如何让信息急速传递，并且归档储存查询，采用之前的纸张记录模式已经不符合
当前使用要求了。所以，对学生请假信息管理的提升，也为了对学生请假信息进
行更好的维护，学生网上请假系统的出现就变得水到渠成不可缺少。通过对学生
网上请假系统的开发，不仅仅可以学以致用，让学到的知识变成成果出现，也强
化了知识记忆，扩大了知识储备，是提升自我的一种很好的方法。通过具体的开
发，对整个软件开发的过程熟练掌握，不论是前期的设计，还是后续的编码测试，
都有了很深刻的认知。
学生网上请假系统通过 MySQL 数据库与 Eclipse 工具进行开发，学生网上
请假系统能够实现考勤管理，课表管理，课程管理，请假管理，系主任管理，老
师管理，学生管理等功能。
通过学生网上请假系统对相关信息的处理，让信息处理变的更加的系统，更
加的规范，这是一个必然的结果。已经处理好的信息，不管是用来查找，还是分
析，在效率上都会成倍的提高，让计算机变得更加符合生产需要，变成人们不可
缺少的一种信息处理工具，实现了绿色办公，节省社会资源，为环境保护也做了
力所能及的贡献。
关 键 词 ：学生网上请假系统；考勤；请假

Abstract
In today's society, with regard to the processing of information, no
enterprise or individual will ignore how to quickly transmit information
and archive and store queries. The previous paper record mode is no
longer in line with current usage requirements. Therefore, in order to
improve the management of students' leave information, and to better
maintain the students' leave information, the emergence of the online
leave system for students has become indispensable. Through the
development of the online leave application system for students, it is not
only possible to apply what you have learned, but also to strengthen the
knowledge memory and expand the knowledge reserve, which is a good
way to improve yourself. Through specific development, I have a good
grasp of the entire software development process, whether it is the
preliminary design or the subsequent coding test, I have a very deep
understanding.
The online leave system for students is developed through MySQL
database and Eclipse tools. The online leave system for students can
realize attendance management, timetable management, course
management, leave management, department head management, teacher
management, student management and other functions.
Through the processing of relevant information by the online leave
application system for students, it is an inevitable result to make
information processing more systematic and standardized. The
information that has been processed, whether it is used for search or
analysis, will be doubled in efficiency, making computers more suitable
for production needs, becoming an indispensable information processing
tool for people, and realizing green office, Save social resources and
contribute to environmental protection.
Key Words：Online leave system for students; attendance; leave
