Entities

An entity defines a structure for copying related data to the subset database.
An entity consists of a driving table and related tables. A driving table is the starting point for defining relationships between tables in the entity. Test Data Manager defines the tables that relate to the driving table based on physical and logical constraints. You can add tables that have cyclic or circular relationships within the table or between tables. You must add a staging connection before you can add these tables to an entity.
When you create an entity, you select a table as the driving table. Test Data Manager retrieves all related tables to the driving table based on the constraints in the driving table. Test Data Manager adds the related tables to the entity by default.
Define filter parameters for columns of tables in the entity. The filter parameters define the criteria for the subset of the data. To define the subset criteria, you can enter a specific value or select a parameter from a list of criteria parameters that you create in the project. You can change the parameter value when you run the workflow to create test data.
You can select a relationship in an entity and specify the minimum and maximum number of child records to generate test data.
