摘要

有人提出一種新的數(shù)據(jù)訪問(wèn)層的N層架構(gòu)的設(shè)計(jì)解決方案。它可以解決多種問(wèn)題，例如：低效率的開發(fā)，移植、更新和重用過(guò)程中的困難。該解決方案采用了.NET的反射技術(shù)和設(shè)計(jì)模式。這種解決方案的一種典型應(yīng)用表明：新的數(shù)據(jù)訪問(wèn)層的解決方案的性能優(yōu)于目前的N層架構(gòu)。更重要的是，應(yīng)用表明：新的數(shù)據(jù)訪問(wèn)層的解決方案可以有效地重用。

Abstract

A new design solution of data access layer for N-tier architecture is presented. It can solve the problems such as low efficiency of development and difficulties in transplantation update and reuse. The solution utilizes the reflection technology of .NET and design pattern. A typical application of the solution demonstrates that the new solution of data access layer performs better than the current N-tier architecture. More importantly, the application suggests that the new solution of data access layer can be reused effectively.
