基于面向对象的图书馆管理系统设计
随着科学技术的发展，计算机技术在图书馆领域得到广泛应用，逐步实现了自动化管理应用系统，在图书馆中发挥着越来越重要的作用。利用现代计算机技术和网络通讯技术，对图书信息进行科学的管理、有效的开发、实现资源共享、实现图书馆的现代化管理，是图书馆的重要内容之一。
本系统以面向对象方法为指导思想，依托Visual Studio.NET开发平台，运用ASP.NET这种全新的面向对象语言。同时，SQL Server 2000将给我们提供强大的后台数据支持，对于问题的分析过程，UML（统一建模语言）将为我们提供直观、科学的软件分析手段。系统功能方面，除了实现基本图书借阅，图书归还，信息多条件查询，超期提醒等功能外，在系统首页更有图书借阅排行榜前二十，让读者和管理员对借阅情况有一个更好的了解。
本报告第一章主要介绍面向对象软件原理及所使用的各种开发工具的概况；第二章是面向对象系统分析，使用UML进行建模，构建系统模型，用可视化的模型将信息用标准化的图形直观地显示出来；第三章是面向对象系统设计，主要是建立与实现有关的模型；第四章主要讨论了系统的实现与运行，并通过测试评价系统可靠性和稳定性。

Abstract
With the development of science and technology, computer technology in the library field is widely used, and gradually achieved automatic management system. In the library it plays an increasingly important role. The use of modern computer technologies and network communication technologies, is one of library's important contents, particularly making sense for the book information of scientific management, effective implementation of the development, sharing of resources, and implementation of modern management.
The object-oriented method for guiding ideology is used this system, relying on Visual studio.net development platform, and ASP.NET, which is a new kind of object-oriented language is also used in this paper. At the same time, SQL Server 2000 will provide us with a strong background data support .For problem analysis process, UML (Unified Modeling Language) is an intuitive, scientific software tool for analysis. For System functionality, in addition to implementing the basic book lending, books returning, information multiple conditional queries and features such as extended reminders, the System Home top 20 of book lending let readers and administrators have a better understanding on borrowing conditions.
The first chapter of this report focuses on the principles of object-oriented software and the use of an overview of the various development tools; The Chapter 2 is an object-oriented system analysis, UML modeling, constructing the system model, using the model of information visualization with standardized graphics display intuitively; The third chapter is an object-oriented system design, and is mainly about the model; The Chapter 4 discusses the implementation and operation of the system, and through the evaluation system to test reliability and stability.
Keywords: libraries, object-oriented programming, C #, UML
