Data Discovery Task Flow

Data Discovery Task Flow

You can run profiles for data discovery to find primary keys and entity relationships between tables in the source data. You can run a data domain profile to search for columns to assign to data domains for data masking.
Before you can run profiles, the administrator must configure a connection to the source database for data discovery. The administrator must also configure connections to the Data Integration Service and the Model Repository Service.
Complete the following high-level steps to perform data discovery:
  1. Create a profile.
  2. Select the type of profiling you want to perform. You can choose to run a primary key profile, an entity profile, or a data domain discovery profile.
  3. If you choose to run a data domain discovery profile, choose the data domains to search for.
  4. Choose the sampling size for the profile.
  5. Run the profile and monitor the job.
  6. After the job completes, open the profile again.
  7. Review the primary key profile results, the entity profile results, and data domain profile results.
  8. Select and approve the results that you want to use for data masking and data subset operations.
