The DataEdit Designer (top window) and forms builder ("the Builder" - bottom window) work together to create data-entry forms from data models. The Designer constructs Entity-Relationship Models (ERMs), represented as a diagram and a catalog. An ERM includes entities, attributes, relationships, and domains. The Builder creates forms from the ERM and automatically handles table links based on relationships defined in the ERM.
