题目：学生请假系统设计与实现
I
摘 要
现代经济快节奏发展以及不断完善升级的信息化技术，让传统数据信息的管
理升级为软件存储，归纳，集中处理数据信息的管理方式。本学生请假系统就是
在这样的大环境下诞生，其可以帮助管理者在短时间内处理完毕庞大的数据信息，
使用这种软件工具可以帮助管理人员提高事务处理效率，达到事半功倍的效果。
此学生请假系统利用当下成熟完善的 SSM 框架，使用跨平台的可开发大型商业
网站的 Java 语言，以及最受欢迎的 RDBMS 应用软件之一的 Mysql 数据库进行
程序开发。实现了学的请假的一个申请功能，老师和管理员可以对学生的请求做
出处理，学生请假系统的开发根据操作人员需要设计的界面简洁美观，在功能模
块布局上跟同类型网站保持一致，程序在实现基本要求功能时，也为数据信息面
临的安全问题提供了一些实用的解决方案。可以说该程序在帮助管理者高效率地
处理工作事务的同时，也实现了数据信息的整体化，规范化与自动化。

Abstract
The fast-paced development of the modern economy and the continuous
improvement and upgrading of information technology have allowed the management
of traditional data information to be upgraded to software storage, induction, and
centralized management of data information. This book lending system was born in
such a large environment, which can help managers to process huge data information
in a short time. Using this software tool can help managers improve transaction
processing efficiency and achieve double the result with half the effort. This book
lending system uses the current mature and perfect SSM framework, cross-platform
Java language that can be used to develop large-scale commercial websites, and
Mysql database, one of the most popular RDBMS application software, for program
development. It realizes the functions of book basic data management, book
borrowing and return, review of registered teacher information, and announcement
information release. The development of the book lending system is designed to be
simple and beautiful according to the needs of the operator. The layout of the function
module is consistent with the same type of website. When the program realizes the
basic requirements, it also provides some practical solutions for the security problems
faced by the data information. . It can be said that this program not only helps
managers efficiently handle work affairs, but also realizes the integration,
standardization and automation of data information.
