Explanation

In database design and entity-relationship modeling, the standard relationship cardinalities are One-to-One (1:1), One-to-Many (1:N), and Many-to-Many (M:N). Options like 'Many to All' and 'All to One' are not standard mathematical or database cardinality definitions and are incorrect.
