Abstract:

A system for updating and reading a data base utilizes a pair of counters working in conjunction with registers located within RAM to enable one upon reading the data base to know if a data base record has been added, deleted, or revised. The system also notifies if the data base is being updated on attempting a read process or during the reading. The updating is performed by a writer that is never inhibited from updating the data base.
