抽象工厂设计模式在数据访问中的应用

设计模式分创建型模式,构型模式,和行为型模式。抽象工厂设计模式是其中的一种,它向客户端提供接口,使得客户端在不必指定具体类型的情况下,创建多个对象。抽象工厂设计模式可以实现一次创建一系列相互依赖对象的需求,在实现数据访问功能中用于提供系统使用数据库的选择,同时也可以降低业务逻辑层和数据访问层之间的耦合。

Abstract Factory Design Pattern in Data Access Application

Designed to create sub-mode model, configuration model, and behavior-based model. Abstract factory design pattern is one of a kind, it provides interface to the client, the client having to specify the specific types of cases, to create multiple objects. Abstract factory design pattern can achieve the first object to create a series of interdependent demand functions in the implementation of data access using the database system used to provide the selection, but also can reduce the data access layer Busine...
