支持演化和迁移的新一代持久对象服务

New Generation of Persistent Object Service for Supporting Evolvement and Migration

文章分析了分布式信息系统的特点,明确提出了在开发和运行分布式信息系统时,持久对象服务需要解决的新问题———对象模型的演化和持久对象的迁移。将反射和元模型技术应用于持久对象服务的设计和构造中,提出了一种反射的持久对象服务体系结构和编程模型。

This paper investigates the features of distributed information system and identifies the new issues,evolve-ment of object oriented model and migration of persistent objects,about persistent object service in development process and at runtime.Applying reflection and meta-model to design and structure persistent object service,the authors provide a system architecture and programming model.
