Research on streamlining data extraction from prodigious data storage is interminable. This book extends a cogent attempt to match concurrent events and high performance processing models for the extraction of data. The author has come up with an idea of parallel approaches namely N folded and Numeral N-folded Mechanism. In N-folded and Numeral N-folded the authors come up with different MONO, DI, TRI mechanisms. This new idea not only reduces the searching time but also reduces the unnecessary comparisons.
