Physical data models (PDMs) are typically created before the logical data model is developed.
False
PDMs include information such as table names, column names, primary keys, and foreign keys.
True
PDMs are important for helping organizations identify and resolve potential performance issues.
True
Database modeling tools cannot help automate the process of creating and maintaining PDMs.
False
