文档介绍：江西理工大学应用科学学院毕业设计 I 学生成绩管理系统摘要学生的成绩管理,是学生信息管理中的一项主要任务,为了及时准确的获取需要的信息,必须对学生信息进行科学的分类和加工。通过系统操作还可以把各种数据串接、储存起来,以提供快速可靠的数据查询。系统设计主要包括五个主要功能模块:权限验证模块、用户管理模块、基础数据库管理模块、成绩管理模块和数据库管理模块。权限验证模块主要是根据用户输入的用户名和密码验证用户身份并且决定其操作权限;用户管理模块实现三个主要功能:添加新用户、修改用户口令和用户权限、删除指定的用户;基础数据管理模块:维护学生信息相关的一些基础数据,它主要包括学校系别设置和各个系别中专业的设置;成绩管理模块:提供学生考试成绩的管理,以及学生总成绩的排名和相关的统计等功能;数据库管理模块:对现有的数据库进行管理,包括数据备份和恢复,以方便用户对数据库的管理和维护工作,提高系统的数据安全性。该系统对硬件和软件要求较低,可以在单机上运行,极大地提高办公效率,实现了学生工作的信息化管理。关键字: 管理信息系统;学生成绩管理系统;数据库余辉辉:学生成绩管理系统 II Student achievement management system Abstract Student performance management, isa main task of students information management, in order to timely and accurate access to needed information, student information must beon the scientific classification and processing. Through the system operation can also use a variety of data string receive, storage, to provide fast and reliable data query. System design mainly includes five major functional modules: authentication based database module, user management module, management module, score management module and database management module. Authentication module is mainly based on the user input user name and password to authenticate users and permissions determine its operation; User management module to achieve the three main functions: add new users, modify user password and the user permissions, delete the user specified; Basic data management module: maintains the student information related to some basic data, it mainly includes the school department don't set and each department in the professional Settings; Performance management module: provides student test scores management, as well as the number of the student's total grade and related statistical functions; Database management module: to manage existing databases, including data backup and recovery, to facilitate the user to the database management and maintenance work, improve the data security of the system. The system of hardware and software requirements is low, can run on sta
