Roadmap for masking data

To mask data, map the source and target data, apply a masking function or procedure, and create a convert service to transform the data.

  1. Create a table map to map the source tables to the target tables that will contain the masked data, as described in Creating a table map.
  2. Edit the table map to define the target data, as described in Editing a table map.
  3. Create a column map to map the source columns to the target columns that will contain the masked data, as described in Creating a column map.
  4. Apply a data masking function or a column map procedure, as described in the following topics:
  5. Create a convert service, as described in Creating a convert service.
  6. Edit the convert service, as described in Editing a convert service.
  7. Test the convert service, as described in Testing a data management service.
