Unfortunately, the widespread used one-to-many, many-to-one, one-to-one, and many-tomany database relationships lack precision and are very often leading to confusions that affect the quality of conceptual data modeling and database design. This paper advocates replacing them with the rigorous math notions of relations and (one-to-one) functions.
