摘  要在现如今的社会，信息技术已经渐渐深入我们的生活，同样我们也已经离不开各种各样的信息处理，这正是运用计算机技术开发信息管理系统的广泛应用形式。计算机技术的最大好处就在于它可以使各个领域的管理变得便捷，应用计算机信息管理系统处理信息，不但有效地提高了其工作效率，同时也增强了其安全性。其中对于相对复杂的信息管理，更能充分体现出它自身的优势。由于飞速发展的信息技术，越来越多的行业开始认识到计算机技术对经营管理的重要性，并努力致力于对信息管理系统的开发。本系统就是为更好地管理图书借还、查询等信息而设计的。

通过对图书馆、书屋等地方的需求调查、分析，再结合所学的C#语言以及数据库技术，设计出了该图书管理系统。该系统主要实现了对图书信息的查阅、图书的借还以及用户信息的管理等功能，其中管理员不仅可以管理所有账户的信息，还可以添加、删除、更新图书信息。68894

本论文主要阐述了图书管理系统的开发背景、需求分析、功能模块的划分以及数据库模式分析,并具此设计了基于C#实现的三层架构系统。

Design and implementation of library management system with C# three tier architecture

Abstract

In modern society, the innovative information technology has gradually penetrated in our life. At the same time, we also can not be separated from the various kinds of information processing, which is using the form of the extensive application of computer technology to develop information management system. Computer technology's biggest progress can make the management of various fields become more convenient.The application of computer information management system information processing, not only effectively improve the work efficiency, and enhance its security. For the relatively complex information management, this system more fully reflects its own advantages. Due to the rapid development of information technology, more and more industries began to realize the importance of computer technology to the management, and strive to focus on the development of information management system. This system is designed for a better management of the books or other goods or information. 

Through libraries, bookstores and other places on the demand investigation and analysis, combined with the study of C# language and database technology design the library management system. The system mainly realizes the consultation to the books information, books borrowing and returning and the management of users’ information and other functions.The administrator can not only manage all account information, but also can do operations like adding, deleting and updating on the information of books. 

This paper mainly expounds the library management system development background, needs analysis, functional module pision and database model analysis, and with this design based on the C# implementation of the three layer architecture system.
