A Prefetching Technique for Object-Oriented Databases

. We present a new prefetching technique for object-oriented databases which exploits the availability of multiprocessor client workstations. The prefetching information is obtained from the object relationships on the database pages and is stored in a Prefetch Object Table. This prefetching algorithm is implemented using multithreading. In the results we show the theoretical and empirical benefits of prefetching. The benchmark tests show that multithreaded prefetching can improve performance significantly for applications where the object access is reasonably predictable. Keywords: prefetching, object-oriented databases, distribution, performance analysis, multithreading, application access pattern, storage management 1 Introduction Two industry trends in the performance/price ratio of hardware systems have implications for the efficient implementation of object-oriented database management systems (OODBMSs) in a client/server computing environment. Firstly, the continuing fall in..
