Design principles and design patterns play a vital role in software development. Over recent years research and development team from both academia and industry have focused on issues related to handling technical debt. Poor design and implementation choices are main reason for high technical debt. Increase rate of technical debt results in code smelling. Adopting suitable design principles and correct design patterns plays a major role to prevent the code smelling. Solving the design problems that occur recurrently in object-oriented software development, several design principles are proposed. Proper understanding and implementing design patterns help indirectly to achieve design principle. In this paper we have briefly explained one of the widely used “SOLID” design principles in object-oriented applications. Discussed applied design patterns to accomplish “SOLID” design principles in our project.
