Development and operation of a database machine for online access and update of a large database

This paper describes the development of a fault‐tolerant database processor (DBP) system to replace OCLC's conventional file system, which not only improves overall system reliability and database availability, but also facilitates the operation and management of a large and rapidly growing online database. This database processor became operational on 16 October 1978, an achievement that represents a significant advance in the operation of information storage and retrieval systems.
