项目介绍
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。
功能介绍
本课题要求实现一套学生成绩管理系统，系统主要包括管理员模块、学生模块和教师等功能模块。
这个系统的功能结构设计如图所示。
