Foreign key constraints define parent-child relationships between the source tables. Use constraints to determine the tables to include in a data subset. You can also limit the values that you want to store in the data subset table columns.
Use data discovery to find relationships between tables. When you identify the relationships that you want to add to the TDM repository, create and edit constraints in Test Data Manager.
The following types of constraints define relationships between tables:
A column or combination of columns that uniquely identifies a row in a data source. A table can have one primary key.
A parent-child relationship between tables based on columns that are not keys. You can create the following logical constraints:
Logical constraints that you accept from data discovery profiles. You can delete these logical constraints.
Logical constraints that you define in Test Data Manager. You can delete these logical constraints.
