摘要： O/R映射是当前基于关系型数据库应用的面向对象系统设计中的新问题，关系型数据库在一定程度上制约了应用系统面向对象设计的架构和灵活性。文中结合已有应用设计架构提出改进的缓冲工作元（Cache Worker）架构，用它可以在兼顾性能的基础上屏蔽关系型数据存储方式给面向对象系统设计带来的障碍，给系统设计更大的灵活性。

Abstract: Object relational mapping has become an important subject in the object-oriented system design, based on relational database application especially in application information system. Relational database has become the bottle-neck in the object-oriented design and application system performance. This paper puts forward a new cache worker framework based on existing framework,which can resolve some problems in this domain. It can enhance system performance and flexibility, as well as mask the difficulty of object-oriented design based on relational database.
