Question

a multivalued composite attribute can be used to depict which of the following weak entity concepts? partially unique attribute identifying relationship a regular (non-identifying) one-to-many relationship between a weak entity and a regular entity a regular (non-identifying) many-to-many relationship between a weak entity and a regular entity all of the above\

Answer 1

A multivalued composite attribute can be used to depict a partially unique attribute identifying relationship between a weak entity and a regular entity.

In a partially unique attribute identifying relationship, the weak entity's identifier includes a foreign key to the regular entity and a multivalued attribute that uniquely identifies the weak entity within the context of the regular entity. This multivalued attribute is represented as a multivalued composite attribute in the ER diagram.

Therefore, the correct answer is: a multivalued composite attribute can be used to depict a partially unique attribute identifying relationship between a weak entity and a regular entity.
