Abstract factory (kit)

Abstract factory pattern is intended to provide an interface if we want to create families of related or dependent objects, but without explicitly specifying their concrete classes:

The preceding class diagram depicts the AbstractFactory class structure and a real-time implementation of an abstract factory pattern for an application that combines a different set of (heterogeneous) products from two different groups (<<Bank>> and <<Loan>>).

The benefits of this are the following:

• Isolating concrete classes
• Making exchanging product families easy
• Promoting consistency among products

Impact is such as; supporting new kinds of the product is difficult.
