Software design is a systematic and iterative process that transforms software requirements into a structured blueprint for implementation. It acts as a bridge between requirement analysis and coding by defining the architecture, components, interfaces, data structures, and interactions of the software system. The design process is not a one-time activity but a repetitive procedure in which the design is continuously refined and improved until it satisfies functional and non-functional requirements. A well-designed software system is easier to develop, test, maintain, and secure. Therefore, the design process is essential for producing high-quality software. The design process begins after gathering and analyzing user requirements. At this stage, designers identify the objectives of the software and prepare a conceptual model of the system. The software is then divided into smaller modules, and the relationships among these modules are clearly defined. This modular approach reduces complexity and makes the software easier to understand and modify. During the design phase, designers also select suitable algorithms, database structures, user interfaces, and security mechanisms that meet business and application requirements. The iterative nature of the design process significantly improves software quality. After preparing an initial design, it is reviewed,
