A Distributed Database Server for Continuous Media Mirette S. Marzouk, W. G. Aref, A. K. Elmagarmid, J. Fan, J. Guo, M. Hammad, I.F. Ilyas, S. Prabhakar, A. Rezgui, S. Teoh, E. Terzi, Y. Tu, A. Vakali, and X. Q. Zhu Return to Demonstrations Abstract In our project, we are adopting a new approach for handling video data. We view the video as a well-defined data type with its own description, parameters and applicable methods. The system is based on PREDATOR, an open-source object-relational DBMS. PREDATOR uses Shore as the underlying storage manager. Supporting video operations (storing, searching-by-content and streaming) and new query types (query-by-example and multi-feature similarity searching) requires major changes in many of the traditional system components. More specifically, the storage and buffer manager has to deal with huge volumes of data with real-time constraints. Query processing has to consider the video methods and operators in generating, optimizing and executing the query plans DiSC'03 © 2003 Association for Computing Machinery
