Question

Quizplus · Accepted Answer

The creation of a relation with primary key and nonkey attributes is a characteristic of a regular entity in the E-R structure. Regular entities have their own primary key attribute, which uniquely identifies each instance of the entity, along with additional nonkey attributes that provide additional information about the entity. Weak entities, on the other hand, do not have their own primary key attribute and rely on a foreign key relationship with a strong entity to determine their identity. Gerunds and IS-A relationships are not relevant to this concept of creating a relation with primary key and nonkey attributes.
