About the Bulk Match Process

The Bulk Matcher performs a sequence of tasks to prepare the master image that will be loaded into the master index database. The first phase groups the records into buckets that can then be distributed to each matcher to process. Records are grouped based on the blocking query. The second phase matches the records in each bucket to one another and assign a match weight. The third phase merges all matched records into a master match file and assigns EUIDs (EUIDs are the unique identifiers used by the master index to link all matched system records). The fourth phase creates the master image of the data to be loaded into the master index database. The master image includes complete enterprise records with SBRs, system records, and child objects, as well as assumed matches and transactional information. The final phase generates any potential duplicate linkages and generate the master image for the potential duplicate table.

The following diagram illustrates each step in more detail along with the artifacts created along the way.
