always made for any input to the screen through the mask processor.
This foreign key is always found with internal tables (without under-

completely within a semantic foreign key. Semantic foreign keys are
part of the data model and are further identified by their dependency
factor and cardinality. Apart from the check on screen entry, they
imply referential integrity conditions.
