Fundamentals of Software Design

Software design and development is one of the most important areas which interest an engineering student. There are a few principles and guidelines that ensure that the software an engineer design should be of high quality, works well and efficiently, and can be edited and extended easily. At the Private B. Tech College in Rajasthan, students are taught about basic principles, fundamentals and procedures involved in Software Design.

Basic Software Engineering Design Principles 

  • Minimizing ‘Coupling’- When you have an interconnected system where various aspects, such as packages, modules, and files, are linked, there can is a risk of multiple problems when one thing breaks off from the line. These connections are termed as coupling. Therefore, it is vital to reduce it as much as possible by making parts independent. 
  • Following the Uniformity Principle- The uniformity principle is one of the noteworthy object-oriented design principles. It means that the software design should pursue the same logic everywhere, and you deal with comparable issues in the same way throughout. It makes the process easier and convenient, instead of creating different solutions for similar problems, which will require more time and effort.
  • Consider Portability- The software’s usability on different platforms and devices significantly impacts its success. It is necessary to think of this fact earlier. If you know that the common people will use applications across various devices, the app can be successful if the designer consider making them portable.
  • Use what Exists- You don’t have to create each and every part of your software from the initation. Numerous existing tools, frameworks, modules, and other instruments can be incorporated into the software. It is advisable to use them efficiently as they can save your time and are likely to work well and be adequately tested. 
  • Review Regularly- The software design should be regularly tested, checked and reviewed in a constantly changing tech world. Otherwise, you will struggle to identify and provide solutions for the issues. 

Some Principles which are taught in Private B. Tech College in Rajasthan to the students for Software Design are-

Single Responsibility Principle- This design principle means that every part of the software creation process should have one purpose.

Open/ Closed Principle- The ‘open’ aspect means that an existing code can be extended to embrace functionality. The ‘closed’ aspect means that when some module is tested, there should be no changes to an existing code unless to fix bugs. 

Interface Segregation Principle- The software creators must break up interfaces into smaller ones to fulfil the requirements and purpose of software designing.
