+The Abstract Document design pattern in Java allows dynamic handling of non-static properties. This pattern uses concept of traits to enable type safety and separate properties of different classes into set of interfaces.
 
 Real-world example
 
-> Imagine a library system where books can have different formats and attributes: physical books, eBooks, and audiobooks. Each format has unique properties, such as page count for physical books, file size for eBooks, and duration for audiobooks. The Abstract Document design pattern allows the library system to manage these diverse formats flexibly. By using this pattern, the system can store and retrieve properties dynamically, without needing a rigid structure for each book type, making it easier to add new formats or attributes in the future without significant changes to the codebase.

 > An object-oriented structural design pattern for organizing objects in loosely typed key-value stores and exposing the data using typed views. The purpose of the pattern is to achieve a high degree of flexibility between components in a strongly typed language where new properties can be added to the object-tree on the fly, without losing the support of type-safety. The pattern makes use of traits to separate different properties of a class into different interfaces.

 > In this scenario, the Abstract Factory is an interface for creating families of related furniture objects (chairs, tables, sofas). Each concrete factory (ModernFurnitureFactory, VictorianFurnitureFactory, RusticFurnitureFactory) implements the Abstract Factory interface and creates a set of products that match the specific style. This way, clients can create a whole set of modern or Victorian furniture without worrying about the details of their instantiation. This maintains a consistent style and allows easy swapping of one style of furniture for another.
