Design policies to mask specific types of data. A policy includes the data domains that describe the data that you want to mask. A policy does not contain any data source. You can apply a policy to more than one project in Test Data Manager.
Define data domains to group sensitive fields by column name or by the column data. Define patterns in the column name or the column data using regular expressions. A data domain also contains masking rules that describe how to mask the data.
To design a data masking rule, select a built-in data masking technique in Test Data Manager. A rule is a data masking technique with specific parameters. You can create data masking rules with mapplets imported into TDM from PowerCenter.
