基于J2EE的网上图书预定系统的设计 摘 要 《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，要应用程序功能的完备易用等特点。主要采用作前端的应用开发工具，利用数据库作为后台的数据库，利用WINDOWS XP作平台采用的ADO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图书的桌面数据。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。 The Design of Online Booking System Abstract 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 systems design.
