Software design is a process used to define the structure, components and functionalities of a software application. Design plays an important role in the success of a software project because properly designed software is easier to manage, easier to maintain and offers higher performance. For design to be used correctly, a good understanding of the needs of the software is first required. This means analyzing users' needs and business requirements, understanding business processes and defining functional requirements. After this step, one of the important elements of design is architectural design. This step is the process of identifying the components of the software, determining their relationships and how they will work together. To unify the design, it is important to utilize design documents when the coding process starts. During the coding process, the software must be created as specified in the design documents. This means that the code is organized correctly and the interconnected modules are compatible. The importance of design for backend and frontend is different. Backend design focuses on building the application's business logic and data management. Backend design is important for creating a scalable, secure, performant and flexible software application. Frontend design focuses on user experience and user interface design. It is important for creating a user-friendly, easy-to-use, responsive and consistent user interface. In conclusion, software design is an important step for the proper creation of the software application. The correct use of design ensures that the software is better managed, easier to maintain and offers higher performance. The importance of design for backend and frontend is different, and a specific approach is required for each.
