To define data subset operations, define the tables that you want to include in the subset database and the relationships between the tables. To perform data masking operations, create a plan to run the masking operations. Add policies for masking the data. You can also add rules that are not in policies.
Perform the following tasks in Test Data Manager to define the data masking and data subset operations:
Create entities, groups, and templates to define the tables that you want to copy to the subset database. An entity defines a set of tables that are related based on physical or logical constraints. A group defines a set of unrelated tables. A template is an optional component that contains the entities and groups.
Assign data masking rules to columns in the data source.
Create a data subset plan, and add the entities, groups, and templates to it. For each column in a parent table, you can define criteria to filter the data.
Create a data masking plan and assign the policies and rules to the plan that you want to apply.
The TDM Server stores projects, entities, groups, templates, and plans in the TDM repository. When you generate and run workflows from plans, the Integration service runs the workflows and loads the data into the target database.
