Abstract: This article is the second in a series to look at ADO.NET. In this installment we take a look at the ADO.NET data storage classes.
The .NET framework provides a series of interfaces, types, and classes in the System.Data second-level namespace that serve as the basis of data access. These definitions are referred to as ADO.NET.
ADO.NET can be conceptually divided into two parts, the data access mechanism and the data storage layer. In the first article in this series I described the interfaces and some of the classes that implement them. These definitions are found in data-specific third-level namespaces under System.Data, such as System.Data.SqlClient, System.Data.OleDb, and System.Data.Odbc.

摘要：。 這文章是在一系列關(guān)于ADO. NET的第二篇，我們在這期中閱讀了“ADO.NET數(shù)據(jù)存取”這篇。
這.NET架構(gòu)提供了一系列接口和類型，以及那些滿足于基本數(shù)據(jù)存取的基本，并在System.Data第二名字空間的類。這些定義參考于《ADO.NET》。
ADO.NET按概念能劃分為兩部分：數(shù)據(jù)訪問機制和數(shù)據(jù)存儲層。在這一系列文章中的頭一篇，我介紹了那些接口以及執(zhí)行它們的類。這些定義諸如System.Data.SqlClient， System.Data.OleDb 和 System.Data.Odbc能在System.Data的第三名字空間的特定數(shù)據(jù)中找到。你通過clicking here能夠讀這篇文章。
