RE: Parent-Child Relationship
The primary need for establishing a parent child relationship is to form a hierarchy of the attribute elements. Eg: Year has a child quater, quater has a child month. In this, we can establish one-many or many to many relationships. Eg: Year has many quarters Quarter belongs to only one year Hope this helps.
