This study presents an improved dual buffering technique providing efficient support Object-Oriented Programming System with a database system. The dual buffer space of OOP environment is partitioned into page buffer pool and object buffer pool. Page buffer manager manages a hash queue of page frame buffers and implements a LRU page replacement algorithm. This paper discusses applying the advanced structure of the hash queue and the improved methods by which the page buffer manager locates blocks in the hash queue. This methods uses efficient LRU algorithm to keep blocks by free list structure on hash queue.
