In this lesson, you learned that address validation compares input address data with reference data and returns the most accurate possible version of the address.
You learned that the address validation process also returns status information on the quality of each address.
You learned that Administrator tool users run the Data Quality Content Installer to install address reference data.
You also learned that the Address Validator transformation is a multi-group transformation, and that you select the input and output ports for the transformation from the port groups. The input ports you select determine the content of the address that is validated. The output ports determine the content of the final address record.
