摘　　要：:针对数据库管理系统中内存管理的单缓冲机制存在的问题 ,提出了适合于 OODBMS中内存管理的双缓冲机制 ,把内存缓冲区分为页面缓冲区和对象缓冲区 ,实现了对缓冲区中对象的有效管理。通过实际应用证明了该机制的有效性。Existing problems in single buffer management mechanism of traditional DBMS are carried through analysis. Double buffer management mechanism which is fit for OODBMS is put forward. Buffer of memory is divided into two parts. One is page buffer,the other is object buffer. The validity of management for objects in buffer is realized.The validity of the mechanism is proved by applied it to a practical system.
