Abstract

Data processing information storage and retrieval system having a memory. A number of modules are interconnected with the memory. Encode and decode modules operate in conjunction with the memory for compacting and expanding data. A revolve module in association with a delta module and a memory enable coded signals to be transferred into a number of unique but equivalent and related signals. A seed module enables the shortest of the equivalent signals to be located. A change module enables any one of the equivalent signals to be updated. An output module causes an equivalent signal to be converted back to the original signal representation. Pipe and brightness modules perform a discrimination function on stored information. The data processor includes programs which by unique means and methods structure and retrieve data from the data base. The retrieval may be based on an inexact match between events and entries of a request and the structured data base.
