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。本学生事务处理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。此学生事务处理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。实现了班级,年级基础数据的管理，场地申请管理，请假申请管理，公告信息的发布等功能。学生事务处理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.
