Data Domain Groups

Data domain groups help you categorize data domains into specific groups. For example, you can group the data domains first_name, last_name, and account_number under the Personal Health Information (PHI) data domain group.
You can create a Personally Identifiable Information (PII) data domain group that includes the Social Security number, first name, and last name. A data domain can be a part of multiple data domain groups. For example, the Social Security number can belong to both Payment Card Industry (PCI) and PII data domain groups. Data domain groups can contain data domains and not other data domain groups.
Note: If you import the data domain file Informatica_IDE_DataDomain.xml after installation, the data domain glossary displays predefined data domain groups and data domains. You can then create more data domain groups as required. To view and change the rules associated with the data domains, import the Informatica_IDE_DataDomainRule.xml file.
