When would you use specialization instead of a regular entity in data modeling?

  • When all entities have a common set of attributes
  • When entities have identical attributes
  • When there is a need for a one-to-many relationship
  • When there is a need to represent unique attributes of a subset of entities
Specialization is used when there is a need to represent unique attributes of a subset of entities within a general category. It allows for the creation of more specific entity types with additional attributes.
