《网上图书预约系统的设计》是以为读者提供便利为前提而开发的一个信息管理系统，它不仅要求建立数据的一致性和完整性，而且还需要应用程序功能的完备、易用等特点。系统主要采用VB.NET作为前端的应用开发工具，利用SQL Server2000数据库作为后台的数据库，利用WINDOWS XP作为系统平台，采用VB.NET的ADO.NET数据访问规范来访问和操作数据库进行开发的供用户管理和操作图书的桌面数据库系统。它的主要功能是实现用户在网上进行图书的预约以及管理员对图书和用户的管理。系统的使用对象可以是高校或者其他单位的图书馆的读者和管理人员。

本论文主要讲述了VB.NET的基本概述及设计方法,紧接着以此系统为例，逐一介绍系统的设计开发，系统分为六个模块：用户身份验证模块、用户个人信息管理模块、图书查询预约模块、信息发布模块、图书管理模块、系统管理模块。在系统分析中先后用系统的功能结构图、数据库的E-R图、数据库表分析了系统所需的各种数据。在系统的设计中，详细的展现了系统的各个功能模块及核心代码。

"The Design of Online Booking System" is a management information system, developed to provide convenience for readers as premise. It not only requires the establishment of data integrity and consistency, but also featured by perfection and easy-to-use to the program function. The system is a desktop database system for users to control and operate books, which mainly adopts VB.NET as front-end application development tool, SQL Server 2000 database as a background database, and Windows XP as a platform. Meanwhile it also uses the ADO.NET data access to standardize of VB.NET for accessing and manipulating the database. Its major function is the realization of booking on-line for readers as well as management of the books and users for the administrator. The system can be used by readers and management staff of libraries in college or other units.

This thesis mainly describes the basic outline of VB.NET and design methods. Then taking this system as an example, it goes through design and development of the system. This system consists of six modules, namely subscriber identification scheme, users pim, books inquiry and appointment, the information promulgation, management of the books, and management of system. The system analyse varieties of data successively with the function chart, the E-R graphic and tables of database. Each functional module and its core codes are displayed for detail in the system's design.
