A design pattern is a description or template for how to solve a commonly occurring problem that can be used in many different situations. There are:

Creational patterns (class instantiation) that can be further divided into class-creation patterns that use inheritance, and object-creational patterns that use delegation.

Structural patterns(class and object composition), class-creation uses inheritance and object-patterns define ways to compose objects to obtain a new functionality.

Behavioral (class’s objects communication) design patterns that are most specifically concerned with communication between objects.

Software design patterns

"A design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn't a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations"(Source making, 2016).

The concept of software design originated in 1994 with the Gang of four (GOF) which is a group of authors: Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides, who wrote a book called Design Patterns - Elements of Reusable Object-Oriented Software which originated the concept.

What are the uses of design patterns?

They are two main uses:
  1. They provide a standard terminology and are specific to particular scenario.
  2. Learning these patterns helps unexperienced developers to learn software design in an easy and faster way.

What are the types of design patterns?

There are 23 design patterns which can be classified in three categories: 
  1. Creational: you can create objects while hiding the creation logic.
  2. Structural: used to compose interfaces and define ways to compose objects to obtain new functionalities.
  3. Behavioral patterns: worried with communication between objects.
