Question

Quizplus · Accepted Answer

In a REA diagram, the maximum cardinality of a relationship can be one or many. This means that one entity can have multiple relationships with other entities, and vice versa. For example, a customer can have many orders, and each order can have many products. It is common for REA diagrams to have multiple many-to-many relationships. Therefore, C) zero or many is incorrect, and A) zero or one is too restrictive. D) none of the above is incorrect, since B is a valid choice.
