This stage matches suspect transactions against a database using the Candidate Finder Stage to query and return potential candidate records.
Transactional Match matches suspect records against candidate records that are returned from the Candidate Finder stage. Transactional Match uses matching rules to compare the suspect record to all candidate records with the same candidate group number (assigned in Candidate Finder) to identify duplicates. If the candidate record is a duplicate, it is assigned a collection number, the match record type is labeled a Duplicate, and the record is then written out. Any unmatched candidates in the group are assigned a collection number of 0, labeled as Unique and then written out as well.
