Configure Parent Child Ratio

Configure Parent Child Ratio

You can select a relationship in an entity and configure the number of child records that you want to generate for each parent record.
In an entity map, you can click a link to edit the constraint between the tables. To generate test data, you can specify the minimum and maximum number of child records for the selected relationship link. When you run a plan, TDM prioritizes the configuration of the child records in the following order: the individual relationship level, the plan level, and the global preferences level.

Configure Parent Child Ratio Example

You want to generate employee details for each department. If you configure the parent child ratio, you can choose to generate 100 to 200 employees for each department, and 1 to 3 employee addresses for each employee. You must select the links individually and configure the minimum and maximum number of child records.
