基于ADO.NET的数据访问助手组件的一种设计方法

A Method of Designing Data Access Helper Components of ADO.NET

以 .NET多层应用程序体系结构为基础 ,充分利用ADO .NET的两个核心组件 :DataSet和一组包括Connection ,Command ,DataReader和DataAdapter对象在内的 .NETFramework数据提供程序 ,采用基本数据访问方法多种重载策略和参数缓存优化策略相结合的机制 ,提出了基于ADO .NET的数据访问助手组件的一种设计方法 。

This paper is based on the muti-tier application architecture for .NET. A method designing the data access helper components grounded on ADO.NET is developed. The method makes the best of the two ADO.NET kernel components: DataSet and a group of .NET Framework data providers including Connection, Command, DataReader and DataAdapter objects. The mechanism of this method adopts a combined scheme of basic data access method muti-overload and parameter cache optimization. A performance analysis of the components is also carried out in the paper.
