1. A system for rationalizing data extracted from a plurality of source systems, said data characterized by a plurality of combinations of data format, data syntax and data element structure, said source systems characterized by a plurality of combinations of hardware, software and operating systems, said system comprising:

  • means for transferring said data from each of said source systems to a host processor;

    means for standardizing said data, said means for standardizing further comprising;

    means for converting said data to a uniform format;

    means for parsing said data to identify first selected data elements; and

    means for binning said first selected data elements into a uniform data element structure;

    means for cleaning said standardized data, said means for cleaning further comprising;

    means for linking data having second selected data elements with recognized equivalent values;

    means for comparing said linked data against standard resources, each of said standard resources characterized by a known data structure including a predefined association of a plurality of resource elements having reliably accurate alphanumeric values;

    means for matching, by recognized equivalence of value thereof, ones of said second selected data elements with ones of said resource elements, so as to identify matched data elements corresponding with matched resource elements; and

    means for updating data having said matched data elements, said means for updating data operable by substituting values in third selected data elements therein with values copied from selected resource elements associated with said matched resource elements;

    means for adding said cleaned data to a single-format database of uniform data structure; and

    means for processing data within said database to create output, said output including data combined from a plurality of said source systems, said output further including data specific to individual ones of said source systems.
