基于.NET的通用数据访问模型的研究与实现

The Research and Application of Universal Data Access Pattern Based on .NET

常用的应用程序对数据库的访问只限于一种特定的数据库,降低了应用程序的可扩展性和灵活性。提出了一种基于.NET的通用数据访问模型,详细阐述了基于ADO.NET技术和简单工厂模式实现通用数据访问模型的设计与实现。该模型可以使应用程序在不修改代码的情况下更换后台数据库,是一种能够应用于当今主流数据库管理系统的数据访问模型。

Being restricted to accessing a specific database in common applications reduces the adaptability of the application and stability.This paper puts forward an Universal Data Access Model Based on.NET.In this paper,it in detail expoundes how to design and achieve universal data access model based on ADO.NET technology and the simple factory pattern.The model needn＇t modify the application code to replace the background database,and can be used in the mainstream of today＇s database management system.
