Using the Index Data Store in Single-Source Analysis

Using the Index Data Store in Single-Source Analysis

Configure a mapping that reads a data source of identity information. Use a Match transformation to compare the data source to the index data store for the master data set.
Before you configure the mapping, verify that the data source contains a column of sequence identifier values.
To save time, you can copy or reuse the mapping that created the index data store.
  1. Open the mapping that generated the index data store.
    Alternatively, open a copy of the mapping.
  2. Verify the data source in the mapping.
    If required, replace the data source with a source that contains the current data.
    If you delete the data source, you also delete the port connections on the Match transformation.
  3. Identify the data source ports that contain the identity information.
    • Connect the identity information ports to the Match transformation.
    • Connect the port that contains the sequence identifier values to the Match transformation.
      The input ports and the input port order must correspond to the input ports on the transformation that created the index tables.
  4. On the Match transformation, select the
    Match Type
    view.
  5. Set the match type to
    Identity Match with Persistent Record ID
    .
  6. Verify the population, key level, key type, and key field values.
  7. Configure the options to identify the index data store:
    • Set the persistence method. For example, select
      Do not update the database
      to preserve the current data in the index tables.
    • Set the matching process to
      Enable
      .
    • On the DB Connection menu, select the database that contains the index tables.
    • On the Persistent Store menu, browse to the tables that contain the index data.
  8. Configure the following properties on the Match Output view:
    • Match. Identifies the records to analyze when the transformation reads index data from database tables.
    • Output. Filters the records that the transformation writes as output.
  9. Perform any other configuration step that the Match transformation requires.
    For example, configure a transformation strategy.
  10. Verify the data target in the mapping.
    If required, replace the data target with another target object.
  11. Connect the Match transformation output ports to the target data object.
  12. Run the mapping.
The mapping compares the data source records with the index data store. The transformation writes the index data for the data source to the data store.
