Test data is sample data that PowerDesigner generates as rows in your database tables to verify database performance or to help in estimating the amount of memory that the database will require. You can generate test data for some or all of the tables in your PDM to an empty or existing database.
Test data generation uses test data profiles (see Test Data Profiles) to define the data to generate. We recommend that you create test data profiles to accurately model your data and associate them with the appropriate columns or domains, but if you have not done so, then default profiles are used.
