I had a very funny teacher and he said Database relationships are just like life relationships.
A one-to-one relationship is a marriage - A man can only have one wife and a woman can only have one husband(at least by law)
A many-to-many relationship is friendship - A man can have lots of friends and a woman can have lots of friends also.
A one-to-many relationship is dating - A men can have lots of dates and a woman can only have one man and walks with an identifier saying to what man she belongs..
The five woman in the class where very mad... why there are so few woman in IT?
