Bubbles for relational database

The mechanical disk storage is limited by long initial delay, few inputs/outputs, and serial access, thus necessitating large complex programs in existing database systems in order to map the user's view into the physical storage and to provide different access paths in response to different queries. Bubble devices are capable of set-oriented processing and associative addressing architecture. This paper presents concepts on data structure, storage structure, and access methods for bubble implementation of relational database. © 1978, ACM. All rights reserved.
