在此文中，我们将深入研究n-tier架构的设计，而且我们将聚焦于DAT (DAT，data access tier) 。
摘要

In this article, we will drill down deeper in to the design of a n-tier architecture and our focus will be on the data access tier (DAT) (Figure 0).Our goal is to design and implement an appropriate data access tier(DAT) for scalable, reliable and interoperable web application. I have divided this article in to two major parts. In the first part, we will discuss about architectural goals, typed DataSet, EventLogs and HttpModules, which are helpful to understand the second part of this article . We will build in the second part a small(but fine) n-tier application and our focus will be on design and implementation of data access tier. You need a SqlServer (database: Northwind) and VS.net to follow this article.
在此文中，我们将深入研究n-tier架构的设计，而且我们将聚焦于DAT (DAT，data access tier) (Figure 0) 。我们的目标是设计并实现一个可升级的可靠并且相互协同DAT网络应用程序。我已将本文分成两个主要的部分。
　在第一部分中，我们将讨论有关于架构的目的，typed DataSet，EventLogs和HttpModules，这有益于理解本文的第二部分。
　在第二个部分中我们将创建一个小的(但是很好) n-tier应程序，而且我们的焦点集中在在设计和实现DAT。
　你需要一个SqlServer (数据库：Northwind )和VS.net来跟随本文进行操作。
