Effective in version 10.1.1, you can create data domains and data domain groups in Enterprise Information Catalog. You can group logical data domains in a data domain group.
A data domain is a predefined or user-defined Model repository object based on the semantics of column data or a column name. Examples include Social Security number, phone number, and credit card number.
You can create data domains based on data rules or column name rules defined in the Informatica Analyst Tool or the Informatica Developer Tool. Alternatively, you can create data domains based on existing columns in the catalog. You can define proximity rules to configure inference for new data domains from existing data domains configured in the catalog.
