![]() And not only that, you can be certain that they were revised multiple times and optimizations were probably implemented. Because Design Patterns often uses by many developers, you can be certain that they work. ![]() For me, the core of Design Patterns consists of the following 6 rules: They Are Proven Solutions ![]() ![]() So Design Patterns are best practices to cover such attributes. And your code should be flexible enough so that it's not too costly to alter. What you decide today could be irrelevant tomorrow. But the most important concern which we often neglect is that you should be able to easily change anything later. They are both equally important to learn.Īs Software Developers, we often evaluate our code through some attributes like how clean, expressive, taking less memory footprint and fast our code is. What you should retain from Design Patterns is that the problem and the solution to the problem are closely related. Design Patterns are not ready to code solutions they are more like a description of what the solution should look like.While Design Patterns states how it should be done. Software Architecture dictates what's going to implemented and where it will be put. Software Architecture is not a Design Pattern.A Design Pattern is neither a static solution nor is it an algorithm, No hard rule of the coding standard.Design Pattern and Principle( SOLID) are two different things.The actual implementation depends on the programming language and even the person that is doing it. It isn't code reuse, as it usually does not specify code.It is popularized by Gang Of Four(1994) book.The more one knows them, the easier it gets to solve all the problems we face.Developers have given a name to solutions which solve a particular type of problem.Design Patterns establishes solutions to common problems which helps to keep code maintainable, extensible and loosely coupled.Design patterns are formalized best practices that the programmer can use to solve common problems when designing an application or system. It is a description or template for how to solve a problem that can be used in many different situations. It is not a finished design that can be transformed directly into source or machine code. In software engineering, a software design pattern is a general, reusable solution to a commonly occurring problem within a given context in software design. So, after taking the online course, YouTube videos, lots of Googling, tons of compiling, and spaced repetition with learning and unlearning, here is what I have gained so far. I barely know how the Flyweight and Classical Visitor pattern work and anyone who says they do is a liar. Some of them I still don't quite understand. Every material, article, explanation, or book was riddled with jargon to sift through. And the first thing I have done is googling "What is Design Pattern?" Hence got the idea of this article.īut as someone without a computer science background (I am from an electronics background), learning them was a struggle. So I have started looking into system/software design and got to know nothing can better start than a Design Pattern. After hitting a certain level of experience and spending quite enough time in the industry, I have realized the importance of designing/architecting system and software.
