AORM持久层框架的设计与实现

针对传统ORM(object-relational mapping)框架使用成本高、执行效率难以控制等缺点,结合软件开发过程中的实际要求,提出了AORM(adaptive object-relational mapping)持久层框架的设计方案。该方案以C#的反射机制为基础,综合考虑软件实际开发过程中的具体要求,结合多种数据库类型的语法特点,建立了以XML关系映射文件与自适应关系映射相结合的AORM持久层框架。与传统ORM框架相比,其最大的特点是将SQL语句独立于应用程序,非常有利于数据库结构的调整和优化。

Design and Implementation of AORM Persistence Layer Framework

Aiming at the disadvantages of traditional ORM(object-relational mapping) framework such as high cost and difficult to control, combined with the actual process of software development requirements, a AORM (adaptive object-relational mapping) persist-ence framework was proposed.This framework is based on the reflection mechanism in C#, considering the specific requirements at actual software development process, combined with the grammatical features of multiple database types, established the persistence framework, which integrates the XML-relation mapping files and auto-relational mapping method.Compared with the traditional ORM framework, the application-independent SQL statements is the biggest feature, and very beneficial to adjust and optimize the database structure.
