6、。而采用人工管理学生成绩的方法，不仅效率低，易出错，手续繁琐，而且消耗了大量的人力资源。为了满足学生成绩管理人员能快速计算、查找、修改学生成绩进行高效的管理，在工作人员具备一定计算机操作能力的前提下，特编写学生成绩管理系统软件以辅助提高教务管理效率。★开发软件名称：学生成绩管理系统★项目开发者：电子学院计算机科学系“学生成绩管理系统”开发小组：张小梅（100202206号，组长），涂莉（100202205号），郝芳（100202204号）1.3参考资料33江国粹等，《数据库建模技术》，安徽电子信息技术职业技术学院计机科学系；二、任务概括2.1目标本系统通过强大的计算机系

7、统技术给教务系统管理人员和学生、老师输入和查看成绩带来便利。本系统除了教务室管理的一般功能以外，还包括网上在线查询成绩信息、查询本人的成绩情况和添加成绩等功能。目标还包括：☆减少人力与管理费用；☆提高信息准确度;☆改进管理和服务;☆更简便，信息化程度更高的成绩管理流程；☆建立高效的信息传输和服务平台，提高信息处理速度和利用率。2.2用户的特点1、本软件的最终用户是面向教务管理员（教务管理员和其它教务管理人员）、查看人员（老师和学生等）。.2、可以比较熟悉操作计算机。教务管理员和老师都是经常性用户。系统维护人员为计算机专业人员，熟悉数据库、
