Gang of Four (GoF) Patterns

A Design Pattern is a template for solving commonly recurring design problems; it consists of a series of elements and connectors that can be reused in a new context. The advantage of using Patterns is that they have been tested and refined in a number of contexts and so are typically robust solutions to common problems. Enterprise Architect provides the Gang of Four Patterns as an MDG Technology that can be loaded into the current repository.

The Gang of Four (Gof) Patterns are a group of twenty three Design Patterns originally published in a seminal book entitled Design Patterns: Elements of Reusable Object-Oriented Software; the term 'Gang of Four' refers to the four authors. Enterprise Architect displays these Patterns in its powerful Pattern engine, helping you to visualize the elements of the Pattern and adjust the Pattern to the context of your software design problem.
