学生成绩管理系统

摘　要

现在我国的大中专院校的学生成绩管理系统还不是很完善，给学校的信息安

全带来隐患，同时也给人们带来很大的负担，浪费了大量的人力、物力。在今天科

技迅速发展的信息时代，改善这种状态，实现学生成绩管理工作流程的系统化、规

范化和自动化显得尤为重要。

本文结合学生成绩管理系统在国内外发展的概况，从需求分析、系统分析、

系统设计、系统实施四个方面介绍本系统的设计和实现过程；其次，本文还简单介

绍了开发本系统所运用的工具 P o w e r B u i l d e r 9.0 及其自带的 A S A数据库、

PowerScript语言；最后，本文对该系统的开发设计进行了归纳总结。

该学生成绩管理系统包括班级、教师、课程、学生、成绩等基本信息的维护

学生成绩的录入和查询，各类综合成绩的运算和提交，奖学金等级的评定、查询和

打印，各重要数据库表的数据备份和数据恢复，以及对已毕业学生所有相关信息的

删除等功能，同时本系统还具有录入高效、查询完整等特点。

本系统的成功开发，旨在给大中专院校的学生成绩管理工作带来一定的方便

减轻广大高校工作者的负担。

STUDENTS’ ACHIEVEMENT MANAGEMENT SYSTEM

ABSTRACT

Now the student achievement management system of colleges at all levels in our

country is generally not perfect, with hidden danger for the school information security

a r i s i n g . A n d t h i s s i t u a t i o n b r i n g s b u r d e n t o t h e p e o p l e i n v o l v e d, w a s ti n g m a s s i v e

develop rapidly, it is especially important to improve this kind of condition and realize

the systematization, the standardization and the automation for the work flow of student

achievement.

Based on the survey of development of student achievement management system

in China and abroad, this paper introduces the process of design and realization from

four aspects: the requirement analysis, the system analysis, the system design, the system

i m p l e m e n t a t i o n. P o w e r B u i l d e r 9. 0 , A S A , a n d P o w e r S c r i p t l a n g u a g e u t i l i z ed i n t h i s

system are also simply introduced. Finally, the paper summarizes the development and

the design of this system.

This student achievement management system includes the maintenance of basic

information, such as class, teacher, curriculum, student, achievement and so on. It also

includes the input and inquiry of student achievement, the operation and submission of

achievement, the evaluation, inquiry and printing of scholarship rank, the data backup

and restoring of each important database table, as well as the deletion of information

concerning graduated students. And this system has many excellences, such as highly

effective input, integrative inquiry and so on.

Successful developing this system will be very convenient for student achievement

management in colleges at all levels, thus lightening the burden of workers concerned.
