This document discusses different types of patterns used in design and architecture. It covers behavioral, creational, and structural design patterns. It also discusses architectural patterns like Model-View-Controller. It provides examples of these patterns and discusses how they can be applied and added to Enterprise Architect modeling tools. It emphasizes that patterns are a starting point and not the final destination.

11. Behavioural PatternsThese design patterns are all about class objects’ communication. Behavioural patterns are those patterns that are most specifically concerned with communication between objects. Creational PatternsThese design patterns are all about class instantiation. These patterns can be further divided into class-creation patterns and object-creational patterns. While class-creation patterns use inheritance effectively in the instantiation process, object-creation patterns use delegation effectively to get the job done. Structural Patterns These design patterns are all about class and object composition. Structural class-creation patterns use inheritance to compose interfaces. Structural object-patterns define ways to compose objects to obtain new functionality.
