Data placement for continuous media in multimedia DBMS

Advances in computing power and the development of high-speed networks have enabled research on interactive and real-time multimedia computing. Nevertheless, the video server in MMDBMS suffers from the limitation of current magnetic disk technology for supporting large amounts of interactive requests simultaneously. We study the problem of data placement in MMDBMS consisting of multiple disks to provide natural retrieval of different portions of video concurrently. Our approach is to disperse video segments onto distributed disks in a restricted round-robin manner. The prime round-robin placement scheme provides uniform load-balance of disks at any rate. In addition, we have shown that the CM server with efficient placement provides appropriate retrieval operations during the execution of other operations.
