Question

Design patterns are recurring solutions to software design problems that are often found in real-world software application development. The underlying concept is based on the design and interactions of the objects involved in the system, and the communication platform between these objects. The goal is the development of elegant, reusable solutions to commonly encountered programming challenges.
As indicated in the text, the Gang of Four (GoF) patterns are generally considered the foundation for all other patterns. They are categorized in three groups: Creational, Structural, and Behavioral. For this discussion, you are to complete the following:

• Research each of the groups of the GoF
• Write a 1-2 page summary of each, providing the following:
  • Description of each design pattern category
  • When it is best to use each pattern
  • Any Overview of the information provided (definition, guidelines listed, etc.)
  • Advantages and disadvantages of using each pattern
• Be sure to include the appropriate links for each source you find.
