An Optical Processing Unit for Relational Database Operations
The management of very large databases (order of hundreds of gigabytes), combined with the real-time response requirement, poses a formidable task even for today's powerful computers. Special-purpose computers dedicated to database management, known as database machines, must provide adequate secondary storage to accommodate the database, high transfer rates to the processing units, and a large degree of parallelism.
