Using inheritance and polymorphism
Talend MDM introduces a true object oriented data model that allows to use inheritance and polymorphic characteristics when defining data models in Talend Studio. For more information, see Creating a data model.
If inheritance and polymorphic characteristics are used when defining data models in Talend Studio, you can have access at runtime to elements extended from other attributes or entities in the data model where you can decide which to choose.
For instance, you can have an address established as a main generic address and at run time defines it as a US or European address.
