Configuring the Match Weight of a Column

Configuring the Match Weight of a Column

For a fuzzy-match column, you can change its match weight in the Edit Match Rule dialog box. For each column,
Informatica MDM Hub
assigns an internal
match weight
, which is a number that indicates the importance of this column (relative to other columns in the table) for matching. The match weight varies according to the selected match purpose and population. For example, if the match purpose is Person_Name, then
Informatica MDM Hub
, when evaluating matches, views a data match in the name column with greater importance than a data match in a different column (such as the address).
By adjusting the match weight of a column, you give added weight to, and elevate the significance of, that column (relative to other columns) when
Informatica MDM Hub
analyzes values for matches.
To configure the match weight of a column:
  1. In the Edit Match Rule dialog box, select a column in the list.
  2. Click the
    Match Weight Adjustment
    If adjusted, the name of the selected column shows in a bold font.
  3. Click the
    button to save your changes.
    Before saving changes, the Schema Manager analyzes the match rule set and prompts you with a message if the match rule set contains certain incongruences.
  4. If you are prompted to confirm saving changes, click
    button to save your changes.
