MADMAN machine

ABSTRACT

A back-end data base machine is discussed in which the back-end is closely coupled to the host system as an intelligent I/O device. The design of the hardware and software is such that the data base disks can be on either the host or back-end computers. The design is motivated by memory size considerations on mini-computer systems and also by cost considerations of large disks. The implementation of such a system on PDP-11s is discussed.
