Architectural considerations of the NEC mass data file subsystem

During the past decade the use of computers in the on-line environment has steadily increased. In particular, there has been a drastic growth of on-line systems for business-oriented applications. We see a shift of interest in computers from their mere computational power to their data management capability, especially in these applications. User demand for the growth of on-line storage capacity in this environment is said to be much larger than the demand for the growth of computational power. We expect the business-oriented computer system to become an information utility in the future.
