Final answer:
The statement is false because an ID-dependent entity has an identifying relationship with its parent entity, meaning it relies on the parent's primary key to form a composite primary key.
Step-by-step explanation:
The statement that a nonidentifying relationship exists between an ID-dependent entity and its parent is false. In database design, an ID-dependent entity, also known as a weak entity, cannot exist without the entity to which it is related, referred to as its parent or owning entity. This relationship is known as an identifying relationship because the existence of the weak entity is entirely dependent on its parent entity, and it often uses the parent's primary key in combination with its own attributes to form a composite primary key.
In a nonidentifying relationship between an ID-dependent entity (child) and its parent, the child's existence does not depend on the parent's existence. This means that the primary key of the parent entity is not part of the child entity's primary key.
For example, let's consider a database representing employees and departments. The employee entity could have a foreign key referencing the department entity. If the relationship between employee and department is nonidentifying, the primary key of the department entity would not be included in the primary key of the employee entity.
