Data Domain Discovery in Informatica Developer Overview
Use the data domain glossary to manage data domains. To create a data domain, you can use predefined data rules and column name rules. You can also generate the data domain based on specific values or patterns in the column profile results.
You can select the source columns, data domains with which you want to match the column data and column name, and sampling options. The sampling options include choosing whether you perform data domain discovery on column data or column name or both. You can also choose the maximum number of rows you want to perform data domain discovery on and the minimum conformance percentage criteria. After you run a profile, you can verify, curate, and drill down on the results. You can also add the results to a data model from the editor in the Developer tool.
