Abstract:
1. A system for index key normalization in a database comprising a processor adapted for: (a) selecting an index key for normalization, wherein the index key contains more than one column, and wherein each column of the index key has a type, and wherein the index key contains more than one type of column type; (b) tracking column normalization, wherein tracking column normalization comprises: (c) generating a normalized value for the index key, wherein generating the normalized value for the index key comprises: (d) generating a marker corresponding to the column, wherein the marker acts as a header for the normalized column value; (e) storing a normalized index key value, wherein the normalized index key value is updated for each column value that is normalized; and (f) appending the marker and the normalized column value to a previously generated marker and normalized column value.
