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成绩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调研需求分析概要设计详细设计编码测试这些步骤基于java语言设计并实现了学生成绩管理系统。该系统基于B/S即所谓浏览器/服务器模式应用java技术选择MySQL作为后台数据库。系统主要包括首页、个人中心、学生管理、教师管理、班级管理、综合成绩管理、专业管理、课程信息管理等功能模块。
本文首先介绍了学生成绩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主要是功能测试、单元测试和性能测试。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。

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 performance management system is one of the products of the information era change. Any system should follow the basic process of system design, this system is no exception, also need to go through market research, demand analysis, outline design, detailed design, coding, testing these steps, based on the Java language design and implementation of student performance management system. The system is based on B/S browser/server mode, the application of Java technology, MySQL as the background database. The system mainly includes home page, personal center, student management, teacher management, class management, comprehensive score management and other functional modules. This article first introduces the dormitory management technology development background and development of the 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 systems overall function module design rendering system function module chart, flow diagram and 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 preliminary completed system is tested, mainly functional test, unit test and performance test. The test results show that the system can achieve the required functions, and the running condition is fair and there is no obvious defect.
