摘要
面向对象数据库管理系统的核心是把现实世界的事物描述为对象．数据库的存储、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．复杂对象中引用了其它的对象．结合我们开发的面向对象的工程数据库管理系统论述了对复杂对象的物理存储、内存映象方法和对象操作方法的实现技术．
How to aBSTRACT objects from entities of real world is one of the keys to object oriented database management system(OODBMS). Implementations of storage, manipulation and management are on objects in OODBMS. Objects can be simple or complex. Complex objects are the objects which reference other objects. This paper uses the object oriented engineering database management system (OOEDBMS) deve loped by us as an example,and discusses the practical technique of physical storage, memory mapping and operation of complex objects.
