三层架构及设计模式(抽象工厂实现)
1. 三层架构实现,把表现层(WebUI)与数据访问层(DAL)分开,使用业务逻辑进行处理(BLL), 避免了把数据信息暴露在表现层, 从而提供了程序的性能,使用业务逻辑处理与表现层进行交互,
把表现层的需求,通过业务逻辑处理,把信息传递给数据访问层进行加工,把加工好的信息,从过业务逻辑又传回表现层, 在整个过程中,业务逻辑层起了中间桥梁作用。在业务逻辑层中, 不能
出现AD0.net 和sql语句的实现。
2. 抽象工厂设计模式,增加了程序之间的开发一致性,保证数据库变化, 不影响程序之间的变化,任何一个层之间变动,都不会影响到正个程序的变化,只需改变其中的一层。
