随着信息技术和网络技术的飞速发展，人类已进入全新信息化时代，传统管理技术已无法高效，便捷地管理信息。为了迎合时代需求，优化管理效率，各种各样的管理系统应运而生，各行各业相继进入信息管理时代，学生考勤管理系统就是信息时代变革中的产物之一。
任何系统都要遵循系统设计的基本流程，本系统也不例外，同样需要经过市场进行调研，论文需求进行分析，概要设计，系统详细设计，测试和编码等步骤，设计并实现了学生考勤管理系统。系统选用B/S模式，应用java技术，MySQL为后台数据库。系统主要包括首页，个人中心，学生管理，教师管理，班级信息管理，课程信息管理，签到信息管理，考勤信息管理，请假信息管理，考勤统计管理等功能模块。
本文首先介绍了学生考勤管理的技术发展背景与发展现状，然后遵循软件常规开发流程，首先针对系统选取适用的语言和开发平台，根据需求分析制定模块并设计数据库结构，再根据系统总体功能模块的设计绘制系统的功能模块图，流程图以及E/R图。然后，设计框架并根据设计的框架编写代码以实现系统的各个功能模块。最后，对初步完成的系统进行测试，对功能、单元和性能进行测试。测试结果表明，该系统能够实现所需的功能，运行状况尚可并无明显缺点。

Abstract
With the rapid development of information technology and network technology, human beings have entered a new information age, traditional management technology has been unable to efficiently and conveniently manage information. In order to meet the needs of The Times, optimize management efficiency, a variety of management systems emerged, all walks of life have entered the era of information management, student attendance management system is one of the products of the information era change.
Any system must follow the basic process of system design, this system is no exception, also need to go through market research, paper demand analysis, outline design, system detailed design, testing and coding steps, design and implementation of the student attendance management system. The system uses B/S mode, Java technology, MySQL as the background database. The system mainly includes home page, personal center, student management, teacher management, class information management, course information management, check-in information management, attendance information management, leave information management, attendance statistics management and other functional modules.
This article first introduces the development background of student attendance management technology and the development status quo, and then follow the routine software development process, first of all, in view of the system and the selection of suitable language development platform, according to the requirement analysis module and database structure design, and then based on the system's overall function module design rendering system function module chart, flow chart and the E/R diagram. Then, design the framework and write code according to the designed framework to achieve each functional module of the system. Finally, the preliminarily completed system is tested for functionality, unit and performance. The test results show that the system can achieve the required functions, and the running condition is fair and there is no obvious defect.
Key words: Student attendance management system; Java technology; The MySQL database
