Data Domain Discovery

Data Domain Discovery

Data domain discovery finds the source columns that contain similar data. The profile assigns the same data domain name to each column that contains similar data. You can assign the same data masking rules to all the columns in a data domain at the same time.
Create a data domain to describe the columns you need to mask with the same data masking rules. When you create a data domain, you configure regular expressions that define patterns in the data or patterns in the column names.
Run the data domain discovery profile to find the columns that match the criteria in the data domain regular expressions. When you configure a profile for data domain discovery, select the tables to search in the data domain discovery operation. Select which data domains to search for in the tables. You can select policies that contain data domains instead of selecting each data domain to search for.
After you run the profile for data discovery you can view the profile results. The profile results assign source columns to data domains. You can choose which profile results to use for data masking.
