What are Software Design Patterns & An Introduction to Factory Design Pattern
As varied as they are, the flanking military maneuver, three-box car design, Sicilian chess defense, and basketball triangle offense have something in common. They have established ways of doing something with optimal efficiency while leaving enough room for introducing variations when faced with an evolving situation.
The keywords here are ‘established’ and ‘efficiency’; the former helps you avoid reinventing the proverbial wheel when trying to solve a problem while the latter ensures you are more productive while doing so.
That also broadly explains what design patterns do for software development. In this brief guide to software design patterns, we look at the concept, why should you use design patterns, and what is the factory design pattern.
What are Software Design Patterns?
Software design patterns are optimized and repeatable solutions to problems commonly faced during software development. Instead of spending time and money solving an already solved problem, design patterns enable developers or an IT business solution provider to write software using tried and tested solutions. Using design patterns leads to standardization, which in turn fosters better communication, faster development, greater code maintainability and adaptability, and more robust software.
That said, it’s important to realize what is not a software design pattern. For instance, it’s not the same as code reuse as it’s language-agnostic, meaning the actual implementation depends upon the programming language you choose.
A design pattern is also different from a software architecture as the latter determines which element of the software will be implemented and where. A design pattern, however, lays out how that ought to be done.
Why Should You Use Software Design Patterns?
One of the principal advantages of design pattern is that it helps you to separate the part of your code that stays the same from the part that keeps changing. This flexibility makes your development process more productive and your app development company, more profitable and competitive.
- Reliability – Design patterns are akin to hand-me-downs from all the developers who’ve come before you, making them refined, reproducible, and reliable solutions to development hurdles.
- Reusability – With design patterns, you can reuse concepts while adapting the actual implementation to your software, speeding up the development process.
- Readability – Design patterns lay down a convention that makes it easier for any developer who knows patterns to understand the code of your system.
- Scalability – The loose coupling of different aspects when using a design pattern allows you to quickly change and expand your code without issues, making your software system more scalable.
- Better communication – Design patterns enhance communication and collaboration in a dedicated development team thanks to an established vocabulary for describing software interactions.
- Saves time and money – One of the main reasons why design patterns are important is they help you save time and money, which makes a huge difference if you hire dedicated resources.
Introduction to Factory Design Pattern
Design patterns lend themselves well to a wide range of problems in software development. In fact, there are different types of software design patterns to tackle the various challenges that developers face when writing software. Among these various types, the factory design pattern is arguably the most popular and widely used among developers.
A prominent reason for its popularity is that the factory design pattern makes the development of large, complex applications simpler. This is a must-have attribute for modern businesses as they grapple with an ever-evolving situation where changes in consumer and market trends are not only fast but often abrupt.
We delve deeper into how factory design helps such businesses keep development costs low while ensuring there’s no drop in development quality, speed, and scalability in our next blog post, Understanding Factory Method with a Factory Design Pattern Case Study.
Summing It Up
Design patterns are time-tested ways of solving software development problems. They offer a standard that developers can use to think and write code. However, you must guard against the tendency of applying them blindly. Software development tends to be iterative and your choice of design patterns needs to acknowledge that and other factors such as available resources and expected future changes.
As an IT business solution provider for close to two decades, we’ve come to understand these nuances about using software design patterns only two well. Our dedicated development team studies your current and future business requirements in detail before committing to the development process, resulting in software that’s scalable, maintainable, and cost-efficient.
