Solution 1

The entity that does not depend on another entity is the Strong Entity.

Here's why:

  1. 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.

  2. 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.

  3. 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.

  4. 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.

Solution 2

The entity that does not depend on another entity is the Strong Entity.

Here's why:

  1. Strong Entity: This is an entity that can exist independently of other entities. It has a primary key and does not need to rely on any other entity for its identification.

  2. Weak Entity: This is an entity that depends on another entity for its existence. It does not have a primary key of its own and relies on the primary key of the entity it is related to.

  3. Multivalued Entity: This is not an entity type but an attribute type. A multivalued attribute can have more than one value for a particular entity.

  4. 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.

So, the answer is Strong Entity.

Solution 4

The entity that does not depend on another entity is the Strong Entity.

Here's why:

  1. A Strong Entity is an entity that can exist independently of other entities. It has a primary key and does not need to rely on any other entity for its identification.

  2. A Weak Entity, on the other hand, is an entity that depends on another entity for its existence. It does not have a primary key of its own and relies on the primary key of the entity it is related to.

  3. A Multivalued Entity is an entity that can have multiple values for a single attribute. This does not necessarily mean it is independent or dependent.

  4. A Derived Entity is an entity that is derived from another entity or entities. It depends on the entity/entities from which it is derived.

So, the Strong Entity is the one that does not depend on another entity.
