A persistent object management system based on Database 一个基于数据库的持久对象管理系统
This paper uses a large object system & PG-RELIEF to review the common requirements of management of persistent objects in large object system. As an example, a unified persistent object management framework based on object-oriented paradigm is presented and analyzed. 以大型对象系统PG-RELIEF为对象,考察一般大型对象系统在持久化管理上的需求,然后提出基于面向对象范型的统一对象持久化框架并对之进行分析。
Using technology of persistent object, named ECO, which is a relational database to object mapping, so that the system had a complete object-oriented programming. 在编码中又采用了持久化对象的技术ECO,也就是关系数据库到对象的映射,使系统的开发完全的进行了对象化编程。
