Similar to the AbstractFactory, this pattern is used to create series of related or dependent objects. The difference between this and the abstract factory pattern is that the static factory pattern uses just one static method to create all types of objects it can create. It is usually named factory or build.

• Zend Framework: Zend_Cache_Backend or _Frontend use a factory method create cache backends or frontends
