kardinaliteitsbeperking
Kardinaliteitsbeperking is a concept used in database design and modeling, particularly in the context of relationships between entities. It specifies the number of instances of one entity that can be associated with an instance of another entity. This helps to enforce data integrity and accurately represent real-world constraints. There are generally four types of cardinality constraints: one-to-one (1:1), one-to-many (1:N), many-to-one (N:1), and many-to-many (N:M).
A one-to-one relationship means that a single instance of entity A can be related to at most
A one-to-many relationship indicates that one instance of entity A can be related to many instances of
A many-to-one relationship is the inverse of one-to-many, where many instances of entity A can be related
A many-to-many relationship signifies that one instance of entity A can be related to many instances of
