In this type of relationship, one entity is associated with multiple instances of another entity
while each instance of the second entity is associated with only one instance of the first entity. This relationship is often referred to as 1:N, where 1 represents the "one" side and N represents the "many" side.


Think of a parent-child relationship. One parent can have multiple children, but each child has only one parent. This is a real-world example of a one-to-many relationship. The parent is associated with multiple children, while each child is associated with just one parent.


Author: An author can write multiple books.
