+## Intent
+Provide an interface for creating families of related or dependent
+objects without specifying their concrete classes.
+
+![alt text](./etc/abstract-factory_1.png "Abstract Factory")
+
+## Applicability
+Use the Abstract Factory pattern when
+
+* a system should be independent of how its products are created, composed and represented
+* a system should be configured with one of multiple families of products
+* a family of related product objects is designed to be used together, and you need to enforce this constraint
+* you want to provide a class library of products, and you want to reveal just their interfaces, not their implementations
+
+## Real world examples

+* [javax.xml.parsers.DocumentBuilderFactory](http://docs.oracle.com/javase/8/docs/api/javax/xml/parsers/DocumentBuilderFactory.html)
