Pattern recognition is an information-reduction process: Text indexing may be supplemented by other syntactic techniques so as to increase its precision or robustness.

By sorting the catalog on different keys, it is possible to produce a variety of indexes as well as subject bibliographies. Although humans are adept at processing information stored in their memories, analog information stored external to the mind is not processed easily.

The result was an analytics management solution that initially reduced a node zCloud cluster to a node cluster running in AWS.
