基于ADO.NET的图书分销管理系统的设计与实现

Micmsoft设计了ADO．NET采处理基于Web的应用程序要求的非连接计算环境，这种非连接设计可以为企业应用程序提供良好的可伸缩性。此外，ADO．NET还提供了一个DataReader对象用于连接模式下的数据库访问。论述了一个基于ADO．NET，采用Visual Basic，NET和SQL Server2000技术相结合的图书分销管理系统的功能与实现方法。从图书分销的操作流程出发，简述了该系统的网络和模块结构，讨论了系统实现中的与Excel数据源通信，增量查询和多线程等关键技术，并给出了主要程序代码。

Book distribution service system designed and realized by ADO .net techniques

Microsoft designed ADO .net technology to handle the computes environment of not linking that requests by the wed-based application, this design could provide the well retractility for enterprise-application. In addition, ADO.net technology also provided a data reader object, which used for the visiting of database in linking mode. With combination of ADO .net, visual basic .net and SQL server 2000 technology, the book distribution service system was developed. The structure of system modal was briefly introduced with the operation flowing of book distribution, The principle of design, network structure, function and realization of the system were described. The key technology of system such as communicate with excel data source, increment query and multithreading technology was discussed, And some code of main program was given.
