Question

Quizplus · Accepted Answer

A dependent entity is an entity that cannot exist without the presence of another entity, which it depends on. Therefore, it can only be present if the entity it depends on is present. Choice A is incorrect because an associative entity is a type of entity used in many-to-many binary relationships, but not all dependent entities are associative. Choice B is incorrect because a dependent entity can also exist as part of a one-to-many or one-to-one relationship. Choices D and E are incorrect because intersection data is only required for many-to-many binary relationships or ternary relationships, respectively.
