Paper Abstract

The management of current and future very large databases necessitates the development of secondary storage with massive capacity and transfer rates as well as highly parallel processing techniques. Parallel read-out optical disks can satisfy both memory requirements and, thus, constitute a suitable candidate for database storage. In this paper, we describe the architecture and functionality of an optical database filter based on parallel optical disks and capable of performing several relational database operations. As the disk rotates, records are retrieved in parallel and compared to search arguments loaded in spatial light modulators. Only data that satisfy a query are allowed to pass through a photodetector to an electronic buffer for further processing. Initial performance analysis has shown that the system is capable of processing data at a rate exceeding one million tuples per second.
