Using Matching Functions
The DataFlow Matching library provides the following functions in the com.pervasive.dataflow.matching.functions package.
Similarity Functions
This collection of functions can be used to compute the similarity of strings. These functions are used to perform "fuzzy" matches between values, attempting to account for common entry errors or other equivalences.
String Encoding Functions
This collection of functions can be used for the phonetic encoding of string values. Phonetic encoding represents words by how they are pronounced. This can be useful for comparing strings such as names, as variant spellings are encoded into the same form.
