Software engineering researchers and practitioners noticed that parts of software projects could often be solved using approaches that were discovered earlier to solve similar problems. This led to the documentation of software design and architectural patterns, which are known solution approaches to a class of problems. 

This course starts by putting software patterns into perspective by answering the question, “What is a software pattern, and how is it different from an algorithm?” You will then learn about the two classes of patterns—software design and architecture patterns. Next, you’ll learn common C++ idioms. Finally, you will learn about software patterns for concurrency. 

By the end of the course, you will have useful and practical tools to improve the quality of your code and productivity. You’ll also be able to analyze a given part of your software project, pick the right pattern for the job, and apply it.

Master Software Design Patterns and Architecture in C++

Let's discuss the history and origin of design patterns by highlighting their past contributors.
 
# Christopher Alexander

Christopher Alexander was an American architect and architectural theorist of the twentieth century. His theories on the nature of human-centered design have impacted many fields other than architecture, such as urban design, software, and sociology. He designed over 300 buildings.

He is most known for his trilogy, *A Pattern Language: Towns, Buildings, Construction*, _The Oregon Experiment_,  and _The Timeless Way of Building_. Some of his later works in _The Nature of Order_, a series of four volumes, have a philosophical and systems analysis tone and develop a comprehensive living system theory.

He is the father of what is known as "design patterns." He used them to logically combine various complicated architectural aspects and structures. He was the first person to coin terms such as pattern, forces, and pattern language in relation to design.  

# Ward Cunningham and Kent Beck 

Alexander's ideas inspired Kent Beck and Ward Cunningham, and they published a book named _Using Pattern Languages for Object Oriented Programs_ in 1987. 
# James Coplien

James Coplien is one of the founders of design patterns in software development history. He worked on C++ idioms and published a book named _Advanced C++ Programming Styles and Idioms_ in 1991. This book is considered one of the most important sources for building design patterns.

# Erich Gamma

Erich Gamma was one of the members of the Gang of Four (GOF) who did a great job in software development and building design patterns. Along with his companions Richard Helm, Ralph Johnson, and John Vlissides, he published a book named _Design Patterns: Elements of Reusable Object-Oriented Software_. This book initiated the concept of design patterns in software development. 

# Frank Buschmann

Frank Buschmann is a senior principal engineer in Germany. He has worked on software architecture, model-driven software development, object technology, and patterns. He has published three volumes of _Pattern-Oriented Software Architecture_ (POSA) along with Regine Meunier, Hans Rohnert, Peter Sommerlad, and Michael Stal starting in 1995.
