摘　　要：面向对象数据库系统(OODBS)的核心是把现实世界的事物描述为对象,数据存储、操作和管理都以对象为依据.对象可以是简单的,也可以是复杂的或复杂对象中引用了其它的对象.首先对OODBS实现过程中复杂对象存储的若干问题进行讨论.具体介绍对象的存储策略、类层次的存储策略和对象的缓冲区管理实现方案.最后就系统的聚簇技术进行详细阐述.How to abstract objects from entities of real world is one of the keys to object-oriented database system(OODBS). Implementations of storage, manipulation and management are based on objects in OODBS. Objects can be simple or complex. Complex objects are those which resemble other objects. Firstly,this article discusses a few problems of complex object storage in the realization process of OODBS. Then,it introduces specifically the storage strategy of the objects,the storage strategy of class hierarchy and the buffer management realization schema. Finally,the clustering techniques of the system are demonstrated in detail.
