If the cache can accurately predict future disk references, access speed will be improved through the use of prefetching. In this paper, the various caching techniques are compared and the queries in an Object-Oriented DataBases are classified into several access patterns. Then we propose an Adaptive Prefetch Caching Method in which both the access patterns of queries and prefetching of the clusters are taken into account. The simulation results for the performance evaluation show that the proposed prefetchng method using the information of the access patterns in queries can achieve better cache performance.
