A two-level architecture for a large data base
Tomás Lang · ACM SIGIR Forum · 1976
A two-level architecture is being proposed for extending third generation computer systems such as the S/370. By attaching a DASD processor to each DASD, performance in large data base applications can be improved. This improvement is achievable without modifying existing data base organization. The DASD processor is very simple and can be implemented using commercially available microprocessors.
