通用数据访问模式的研究

Research on Universal Data Access Pattern

运用面向对象的设计原则,将代理模式与工厂方法模式相结合,提出了一种新的通用数据访问模式。该模式可支持多种关系型数据库管理系统和数据驱动程序,通过将应用层与数据层隔离,大大减少了系统的耦合性,具有广泛的实际应用前景。

Using some object oriented design principles, this paper introduces a new universal data access pattern which supports multiple RDBMS and data driver components combined with proxy pattern and factory method pattern. It reduces the coupling of system greatly through separating the data layer from application layer and has a broad practically application foreground.
