A compound field is automatically created in response to a trigger event. In one aspect, a user selects a field type and a compound field associated with the field type is automatically created. A compound field can be manipulated and presented as a single conceptual unit in a user interface (e.g., a form, screen or layout) of an application (e.g., a database application). When an object representing the compound field is dragged and dropped or otherwise selected in the user interface, the compound field is expanded to reveal one or more subfields capable of receiving data from a user. In another aspect, one or more background tables are automatically and transparently created to store compound field objects. In another aspect, a user can create their own compound field types.
