While it could be a good approach for a good design but still there is a problem associated with this, and problem is when it comes time to change design, it realize it’s too late to change design. Changes and updates will inevitably arise. What is Good Software? Avoid code repetition. It suggests not to involve complexity in your code, and try avoiding it as much as you can. So that whenever same type of requirement is there, concerned method of that service or layer can be invoked. Crisp point to remember here is when our code is talking with other pieces of code, it always increases coupling. In the context of object-oriented design, this could be achieved with the concept of Abstraction and Polymorphism. Graphic design is a highly sought-after skill. This principle says that our code should be cohesive in nature. If proper time is given to the designing factor of the SDLC then at a later point of time it will not take much time to modify and survive with the latest changes. Note – The hardware architecture (the software architect in turn provides requirements to the system architect, who configures the hardware architecture). Keep It Simple, Stupid (KISS) Principle : It is very first principle, acronym stands for Keep It Simple, Stupid. Photograph by Abisag Tüllmann 1. Fundamental Principles of Good Software Design. 1. Encapsulate What Changes . Please Improve this article if you find anything incorrect by clicking on the "Improve Article" button below. Don’t Repeat Yourself is the principle that any code in your program should only be written once, and never duplicated. © 2020 - EDUCBA. Software is treated as a good software by the means of different factors. This principle talks about coupling. Software designing should be simple. Always place code that you’re likely to use again in a utility class and make it accessible throughout the application. In context of object-oriented design, it is well said that a class should have only and only one responsibility so that it has to change less frequently. These principles embody more than 40 years of academic research and industry experience, passed to us from previous generations of software engineers. This principle works behind extreme programming (XP) but it is applicable in all kinds of software development processes and methodologies. Once development of software or component is completed, it must go for a code review process before pushing it to next stage. Refine your knowledge of software design patterns and principles with this guide. How to set input type date in dd-mm-yyyy format using HTML ? Software design principles are the principles that are mandatorily needed to get the software to become bug-free and not to make the software getting on the verge of an end. Analysts generate instructions for the developers about how code should be composed and how pieces of code should fit together to form a program. On the other hand when a piece of code is broken into several pieces where each piece does one and only one thing well, then cost of changing that piece is much easier. Balance, proportion and rhythm in a space bring the elements of color, pattern, texture and shape into a functional relationship with the physical aspects of space, light and structure. 2. The following programming principles have helped me over the years become a better programmer, and I believe can help any developer become more efficient and to produce code which is easier to maintain and that has fewer defects. CHAPTER 2 Principles of Good Software Design. Since I wrote my article recently about Google’s 9 principles of innovation a reader over on Reddit pointed me to a resource on some more good design principles. lesson: design for change!
