摘要本毕业设计主要是实现一个操作简单、查询方便、安全、准确的学生信息管理系统。工作目的是通过本系统改变之前繁琐的人工操作方式，解决人工操作带来的一些问题。在设计本系统之前，我先了解了具体的需求，从而确定了基本的框架，再进行数据库的建立以及系统代码的编写和系统的维护，完成了一个相对简单实用的学生信息管理系统。

本系统主要划分了两大模块，学生可以登录查询自己的成绩，主要的还是管理员的登录，涉及学生、教师、班级、专业、学生成绩等信息的增删改查功能，很好的完成了本系统的需求。本系统基于三层架构、使用C#语言来实现，SQLServer为数据库来进行设计与开发。68887

Design and implementation of student information management system based on a three-tier structure

Abstract

The primary aim of this graduation project is to realise an easy, convenient, safe and accurate student information management system. This system can change previous cumbersome manual operation and solve a few problems brought in by it. Before designing this system, I learn about the specific demands to set up a basic framework before building up database and coding and maintaining the system, which contributes to a relatively easy and convenient student information management system.

This system can pide into two modules. One is that the students can log in to check their own results. More importantly, another is that the administrator can log in to carry out the functions of adding, deleting, correcting and checking, involved in the information such as students, teachers, classes, majors and results. Therefore, the demands for this system have been highly satisfied. It is based on a three-tier structure, achieved by C# language and taking SQL Server as the database to conduct design and development. 

Key Words: three-tier structure  student information management  system
