Abstract

The storage management of an interactive multimedia information system (MMIS) is different from that of the conventional file system. In an MMIS, there could be relationships between the homepages stored on a disk. During browsing homepages, how to reduce the disk seek time and then to provide a fast browsing become a critic performance issue. In the paper, we propose two data placement algorithms for continuous and non-continuous spaces to place objects on a disk in order to reduce their access time. In the simulation, we conduct several experiments to validate the superiority of our algorithms over other algorithms. Besides we also show that the results derived by our algorithms are near optimal by comparing with the optimal solution.
