Polymorphic association
From HandWiki
Polymorphic association is a term used in discussions of Object-Relational Mapping with respect to the problem of representing in the relational database domain, a relationship from one class to multiple classes. In statically typed languages such as Java these multiple classes are subclasses of the same superclass. In languages with duck typing, such as Ruby, this is not necessarily the case.
