Which of the following set should be associated with weak entity set for weak entity to be meaningful?
A. Neighbour set B. Strong entity set C. Owner set D. Identifying set
Explanation: Every weak entity must be linked to an identifying entity; in other words, the existence of the weak entity set is contingent on the presence of the identifying entity set. The weak entity set that the identifying entity set identifies is said to be owned by the identifying entity set. Owner entity set is another name for it.
