A method of generating attribute cardinality maps

摘要: This invention provides a novel means for creating histogram use in minimizing response time and resource consumption when optimizing query database, other like structures, the being created by placing ordered elements into specific range until next element to be considered inclusion is predetermined distance from (generalized) mean value associated with within range, whereupon that placed following range. Similarly, ranges are closed greater than For each location size of recorded with, example, value, slope or attribute characterizing one more The has also applications pattern recognition, message routing, actuarial sciences.
