High speed relational data base processor

摘要: The present invention is a data base information engine subsystem which examines on the fly as it retrieved from mass storage device (i.e., disk), and before storing in memory, to select only specified elements of required by host computer according criteria set forth computer. A page mapper circuit separates command processing access for command. instruction used contains optimizing algorithms parse reorder operation be most efficient (with respect time). also high speed processor special purpose designed optimized retrieval while doing operations at speed.
