Question

Quizplus · Accepted Answer

N:M relationships can have more than one entity on each side of the relationship, meaning that multiple records from each table can be related to each other. This is different from one-to-many relationships, which have one entity on one side and multiple entities on the other side. Option A is incorrect because N:M relationships are not the same as N:N relationships, which do not exist in database design. Option B is incorrect because N:M relationships do not represent minimum cardinalities, but rather the possibility of many-to-many connections. Option C is incorrect because one-to-many relationships are different from N:M relationships in terms of the number of entities on each side of the relationship. Option E is incorrect because N:M relationships connect the same data types, but allow for many-to-many connections.
