Problem Statement

Patterns are often classified into creational, structural, and behavioral categories. However, this leaves a large number of patterns in each group, with no easy way of remembering all of them. What classifications and strategies have been developed to help programmers remember patterns, so that they can apply them at opportune moments?

A design pattern in software engineering can be described as a reusable solution template to a frequently occurring software design problem.

  • Purpose
  • Scope
  • Functionality
  • Structural Principles
