摘要
ORM(Object/Relation Mapping),即对象/关系数据库映射。ORM框架就是为了解决面向对象程序设计语言与关系型数据库之间"阻抗不匹配"而产生的,这种框架能将业务逻辑层和持久层有效分离,使两层之间以松耦合方式衔接起来,便于代码的维护。探讨了ORM框架的实现机制。
ORM is object / relation database mapping.The generation of ORM framework is to solve the ＂impedance mismatch＂ problem between object-oriented programming language and relational databases.It can effectively separate the business logic layer from persistence layer,making the two layers link up in loosely coupled,to maintain code.This thesis is mainly to discuss the implementation mechanism of ORM framework.
