Defining Data Dictionary Parent, Child and External Relationships

Data Dictionaries need to know how to model relationships. This is accomplished by:

• Defining all related-to parent tables
• Defining all relation-from child tables
• Defining any extra tables that are required

Once defined, your Data Dictionary objects can use this information to verify that DDO structures are properly configured for save and delete operations.
