Question
………….
Does not depend on another Entity.
- Strong Entity
- Weak Entity
- Multivalued Entity
- Derived Entity
Solution
The entity that does not depend on another entity is the Strong Entity.
Here's why:
-
Strong Entity: This is an entity that can exist independently without needing to rely on any other entities. It has a primary key that uniquely identifies its instances. Therefore, a strong entity does not depend on another entity.
-
Weak Entity: This is an entity that cannot exist without a 'parent' entity. It does not have a primary key of its own and relies on the primary key of its 'parent' entity. Therefore, a weak entity depends on another entity.
-
Multivalued Entity: This is not an entity type but an attribute type. A multivalued attribute can have more than one value. It does not indicate any dependency or independency of an entity.
-
Derived Entity: This is also not an entity type but an attribute type. A derived attribute is an attribute whose value is calculated from other attributes. The entity that has a derived attribute can be either a strong or weak entity.
So, the answer is the Strong Entity.
