Design Patterns: Catalog

Design patterns are known solutions to complex requirements — examples of such requirements might be decoupling two objects. There are three catalogs of design patterns:

1. Creational Patterns — provide various object creation mechanisms, which increase flexibility and reuse of existing code.
2. Structural Patterns — explain how to assemble objects and classes into larger structures while keeping these structures flexible and efficient.
3. Behavioral Patterns — concerned with algorithms and the assignment of responsibilities between objects.
