Associative mass storage for database

ABSTRACT

Two types of associative mass storage for use in database systems, have been introduced in this paper, they are I Hybrid associative storage For use as an associative primary storage, it comprise a storing “basement” and an associative surface matrix. The suggested configuration has a capacity of up to 64 megabytes and a search rate of the order of 2 to 8 gigabytes per second. As well as associative operation, it is also suitable for extremely fast sorting. II Hardware hash coding system A hardware structure provides associative access to conventional, numerically addressed storage media. The prefered application is for quasi-associative access to data in secondary storages. Associative mass storages systems differ in their characteristics and complement each other. Together they form the hardware building blocks of a database system.
