Introduction

Design patterns are used in software development to help developers deliver high-quality and maintainable code. This post will help you learn what a design pattern is, why they're useful, and how to make the best use of them.

What is a Design Pattern?

A design pattern is a solution to a common software design problem. A design pattern is not the same thing as a framework, an architectural pattern, or even a design principle.

A framework is a collection of classes and functions that provide functionality that you can use in your program without having to write any code yourself. For example, when you create an iOS app using Swift or Objective-C, you are building around the iOS framework which gives you things like window management and user interaction built into your application by default. Apple provides thousands of libraries (known as frameworks) for developers to use in their apps that make it easier to build apps quickly because all the work has already been done for them by Apple engineers who spent many years doing this work before opening up their source code so other people could benefit from their hard work too!

The idea behind architectural patterns is that there are repeatable solutions for problems such as how do we organize our programs? And how can we manage dependencies between different pieces so that if one piece changes then everything else doesn't break at once? These solutions fall under categories such as "Inversion Of Control" where objects rely on each other instead of directly calling each other from within themselves (dependency injection), which makes changes easier since nothing else needs updating when one object changes its behaviour - just its dependency will change automatically through wiring relationships defined previously

History Of Design Patterns

Design patterns are not a new concept. They’ve been around since before the advent of modern computing, and they have evolved alongside it. You may be surprised to learn that the origins of design patterns can be traced back to ancient Rome and Greece!

The first written documentation on the topic was an article by Christopher Alexander entitled “A Pattern Language”. This book described how communities were able to create their own thriving culture through their use of pattern language a set of various building blocks (or patterns) that could be combined in different ways and reused as needed. For example, you might find a pattern for “carpentry” or “masonry” in your local library; these represent basic architectural elements that are relevant across many different types of buildings regardless of size or function (e.g., walls).

Why You Should Be Using Design Patterns For Your Software Projects?

Design patterns are proven solutions to common software development problems. They're reusable and can be used in many different contexts.

Because of their usefulness and flexibility, design patterns are a good way to communicate with other developers when you work on a project. They also help create a pattern-oriented software architecture that improves maintainability, readability, and reusability of your code base.

Types Of Design Patterns

  • Creational Patterns

  • Structural Patterns

  • Behavioral Patterns

  • Concurrency Patterns

  • Component Patterns

  • Interaction Patterns * Constraint Patterns * State Patterns

What Are The Benefits Of Using Design Patterns?

In a nutshell, design patterns are a set of guidelines that help you create software in a more structured and efficient way. The main benefits of using design patterns include:

  • Reducing the complexity of your software

  • Reducing the time it takes to create your software

  • Reducing the time it takes to maintain your software

  • Reducing the time it takes to test your software

Best Practices When Choosing A Design Pattern To Use In Software Development Projects

  • Know the problem you are trying to solve. This sounds like it should be obvious, but it's often not. If you are using a design pattern, there is a reason for it. Design patterns have been developed based on years of experience by software engineers who have built hundreds or even thousands of applications in various industries and domains throughout the world.

In order for a design pattern to provide value, you must understand what kind of problems it solves (as well as those that might arise from its use). For example:

  • Is your application going to be deployed on traditional hardware? Or will it run in a web browser?

  • Will users interact with your application via touchscreens? Or do they interact by clicking buttons or selecting menu items? Design patterns such as Model-View-Controller (MVC) may offer valuable benefits when building rich desktop apps but can cause significant performance issues when used in web browsers.

Best Practices And Tips When Implementing Design Patterns In The Software Development Process

Use a design pattern to solve a problem.

Use pattern language to help you implement a design pattern.

Use the software development process to implement your solution for the problem that you have solved with the design pattern (or vice versa).

A Pattern-Oriented Software Architecture Can Simplify Your Software Development Processes

Pattern-oriented software architecture can simplify your development processes.

Patterns are reusable solutions to common problems.

They're a great way to reduce the complexity of your software project, and they can help you avoid mistakes.

Conclusion

The principles of pattern-oriented software architecture will help your team achieve better project results. To get started, try to adopt some of these practices and you’ll see an immediate improvement in how smoothly your project is going. For example, using well-defined design patterns will allow everyone on the team to communicate clearly about what they are doing without having constant meetings or email chains trying to figure out who is working on what part of the software project management process. If people can just say “I’m using an Adapter Pattern here” then everyone knows exactly what that means because we all know what an Adapter Pattern does!
