Overview

Before starting off with design patterns for Ruby we need to define what a design pattern is, Design patterns can be described as "a general reusable solution to a commonly occurring problem in software design." [1] The idea of design patterns is to not to reinvent the wheel but to solve the current problems by using solutions that have worked in the past. A design pattern names, abstracts, and identifies the key aspects of a common design structure that make it useful for creating a reusable object-oriented design. It helps to identify the classes and instances and the way they collaborate with each other to form a solution to a problem. Design patterns c an be classified into 3 parts Creational, Structural, Behavioral (See if we can give links for these.)
